On comparing a number of crocodile-arrows with the animal itself, one is struck with the numerous realistic details which have survived the decorative treatment of the design. It must be remembered that one is dealing with a work of decorative art, and not an attempt at realistic carving. In one arrow several anatomical characteristics of the crocodile will be suggestively rendered; in a second other details will be more accurately carved; but in the great majority of arrows belonging to this series, variation has occurred to such an extent that the crocodile becomes almost unrecognisable as such.
A very typical crocodile arrow is to be seen in Fig. [6], A; the chief variation in this is the placing of one nostril behind the other.
In Fig. [6], B, the nostrils are side by side, and the teeth of the upper jaw are represented by a zigzag line. The hind-limbs and the tail are entirely absent.
Fig. [6], C, is important in several respects. The nostril is single, the mouth is partially closed; but the teeth have not, as yet, entirely disappeared from the hinder closed moiety. The eye is oval, a rare feature, and the dorsal scales of the neck are represented; this is also rare. The fore-limbs have been converted into a raised zigzag band, which encircles the arrow. The hind-limbs do the same, except that the pattern is interrupted in the median dorsal line by a double row of tubercles, which represent the prominent dorsal scutes of this region in the living animal. The thigh is carved with a curved upper border and a straight lower border.
There is rather a gap in the series between Fig. [6], C and D; but it is easy to see that the hinder part of the mouth is closed, and the teeth of both jaws are represented by different patterns; the front part of the mouth is widely open, but edentulous. The nostril is single. The eye has become enormously enlarged, and constitutes what I propose to term an eye-panel; it extends backwardly to the fore-limb. The plain upper surface of the head and neck has become much reduced, owing to the encroachment of a double row of spots on each side. The artist mistook the upper for the lower surface when he carved the fore-limbs, for it will be seen that the toes are above and the dorsal scutes are placed below. Another point of interest is the replacing of the central row of caudal scutes by a plain ridge; so far as I am aware this is unique.
Fig. [6], E, is a type of a large number of arrows. The front open part of the mouth is quite small, and the surfaces of the jaws are scored by oblique lines. The median dorsal plain band of the snout is no wider than the lateral bands which indicate the closed hinder part of the mouth. In the gape of the mouth an elongated triangle is very generally present; this is doubtless intended to represent a tongue. Sometimes it is notched. The eye-panels are elongated and narrow, and the dorsal median band of the head and neck extremely reduced. The rest of the body in this arrow calls for no special mention. Sometimes eyes are carved on the dorsal surface of the gaping end of the upper jaw.
In the last arrow (Fig. [6], F) of the series which I figure, the front part of the mouth has disappeared; but the hinder part of the head is much the same as in the last arrow. The fore-limbs and body are absent. The hind-limbs are narrow, but retain their characteristic forward bend; the dorsal caudal scutes are replaced by numerous parallel transverse lines.
