1: Species of the true Tarentulæ are not uncommon in Ceylon; they are all of very small size, and perfectly harmless.
By day it remains concealed in its den, whence it issues at night to feed on larvæ and worms, devouring cockroaches[1] and their pupæ, and attacking the millepeds, gryllotalpæ, and other fleshy insects. The Mygale is found abundantly in the northern and eastern parts of the island, and occasionally in dark unfrequented apartments in the western province; but its inclinations are solitary, and it shuns the busy traffic of towns.
1: Mr. EDGAR L. LAYARD has described the encounter between a Mygale and a cockroach, which he witnessed in the madua of a temple at Alittane, between Anarajapoora and Dambool. When about a yard apart, each discerned the other and stood still, the spider with his legs slightly bent and his body raised, the cockroach confronting him and directing his antennæ with a restless undulation towards his enemy. The spider, by stealthy movements, approached to within a few inches and paused, both parties eyeing each other intently: then suddenly a rush, a scuffle, and both fell to the ground, when the blatta's wings closed, the spider seized it under the throat with his claws, and dragging it into a corner, the action of his jaws was distinctly audible. Next morning Mr. Layard found the soft parts of the body had been eaten, nothing but the head, thorax, and elytra remaining.—Ann. & Mag. Nat. Hist. May, 1853.
Ticks.—Ticks are to be classed among the intolerable nuisances to the Ceylon traveller. They live in immense numbers in the jungle[1], and attaching themselves to the plants by the two forelegs, lie in wait to catch at unwary animals as they pass. A shower of these diminutive vermin will sometimes drop from a branch, if unluckily shaken, and disperse themselves over the body, each fastening on the neck, the ears, and eyelids, and inserting a barbed proboscis. They burrow, with their heads pressed as far as practicable under the skin, causing a sensation of smarting, as if particles of red hot sand had been scattered over the flesh. If torn from their hold, the suckers remain behind and form an ulcer. The only safe expedient is to tolerate the agony of their penetration till a drop of coco-nut oil or the juice of a lime can be applied, when these little furies drop off without further ill consequences. One very large species, dappled with grey, attaches itself to the buffaloes.
1: Dr. HOOKER, in his Himalayan Journal, vol. 1. p. 279, in speaking of the multitude of these creatures in the mountains of Nepal, wonders what they find to feed on, as in these humid forests in which they literally swarmed, there was neither pathway nor animal life. In Ceylon they abound everywhere in the plains on the low brushwood; and in the very driest seasons they are quite as numerous as at other times. In the mountain zone, which is more humid, they are less prevalent. Dogs are tormented by them; and they display something closely allied to cunning in always fastening on an animal in those parts where they cannot be torn off by his paws; on his eyebrows, the tips of his ears, and the back of his neck. With a corresponding instinct I have always observed in the gambols of the Pariah dogs, that they invariably commence their attentions by mutually gnawing each other's ears and necks, as if in pursuit of ticks from places from which each is unable to expel them for himself. Horses have a similar instinct; and when they meet, they apply their teeth to the roots of the ears of their companions, to the neck and the crown of the head. The buffaloes and oxen are relieved of ticks by the crows which rest on their backs as they browse, and free them from these pests. In the low country the same acceptable office is performed by the "cattle-keeper heron" (Ardea bubuleus), which is "sure to be found in attendance on them while grazing; and the animals seem to know their benefactors, and stand quietly, while the birds peck their tormentors from their flanks."—Mag. Nat. Hist. p. 111, 1844.
Mites.—The Trombidium tinctorum of Hermann is found about Aripo, and generally over the northern provinces,—where after a shower of rain or heavy night's dew, they appear in countless myriads. It is about half an inch long, like a tuft of crimson velvet, and imparts its colouring matter readily to any fluid in which it may be immersed. It feeds on vegetable juices, and is perfectly innocuous. Its European representative, similarly tinted, and found in garden mould, is commonly called the "Little red pillion."
MYRIAPODS.—The certainty with which an accidental pressure or unguarded touch is resented and retorted by a bite, makes the centipede, when it has taken up its temporary abode within a sleeve or the fold of a dress, by far the most unwelcome of all the Singhalese assailants. The great size, too (little short of a foot in length), to which it sometimes attains, renders it formidable; and, apart from the apprehension of unpleasant consequences from a wound, one shudders at the bare idea of such hideous creatures crawling over the skin, beneath the innermost folds of one's garments.
At the head of the Myriapods, and pre-eminent from a superiorly-developed organisation, stands the genus Cermatia: singular-looking objects; mounted upon slender legs, of gradually increasing length from front to rear, the hind ones in some species being amazingly prolonged, and all handsomely marked with brown annuli in concentric arches. These myriapods are harmless, excepting to woodlice, spiders, and young cockroaches, which form their ordinary prey. They are rarely to be seen; but occasionally at daybreak, after a more than usually abundant repast, they may be observed motionless, and resting with their regularly extended limbs nearly flat against the walls. On being disturbed they dart away with a surprising velocity, to conceal themselves in chinks until the return of night.
