[Plate XIII.], p. 183, fig. A.—Silk lining of tube of Atypus piceus (Sulz.), taken at Troyes in Champagne, and communicated to me by M. E. Simon; B, drawing of portion of nest of Cyrtauchenius elongatus (Sim.) made after the description of the discoverer, and subject to his (M. E. Simon's) corrections. This is the only illustration in the present work not taken from an actual specimen. These figures are of the natural size.
[Plate XIV.], p. 193.—Diagrams of the known types of trap-door nest. Fig. A, nest of Atypus piceus (Sulz.); B, nest of cork type; B 1, the layers of silk with earth rims of which a cork door is composed; C, single-door unbranched wafer type; D, single-door branched wafer type; E double-door unbranched wafer type; E 1, lower door of the same, of the natural size; F, Hyères double-door branched wafer type; F 1, lower door of the same, of the natural size; G, and G 1, double-door branched cavity wafer type. At G 1 the perfect type is seen, while at G, the descending cavity, the outlines of which are indicated by dotted lines, has been filled up; G 2, lower door of the same of the natural size. (Figs. A, B, C, D, E, F, G and G 1, diagrammatic representations of nest on a reduced scale, Figs. B 1, E 1, F 1 and G 2, of the natural size).
[Plate XV.], p. 198, fig. A.—Nest of Cteniza Californica (Camb.) nearly entire, enclosed in the clayey earth of the bank from which the specimen was taken, the door being artificially represented as being partly open; A 1, door of the same as seen when closed; B, Cteniza Californica (Camb.) from a living specimen; B 1, the same seen in spirits, the legs not represented; B 2, the same seen sideways; (figs. A, A 1, B, B 1 and B 2, are of the natural size); B 3, the eyes, greatly magnified; B 4, the three claws terminating the tarsal joint of the hindmost left leg; B 5, line representing the measured length of the spider excluding the falces and spinners, the uppermost division gives the length of the caput terminating at the half-moon-shaped fovea, the middle division that of the thorax, and the lowest that of the abdomen, while the transverse line gives the breadth of the cephalothorax; B 6, eggs laid by the spider in captivity on the under side of the gauze which covered the box (the position is reversed here) of the natural size; B 7, the same magnified; B 8, another group of eggs, magnified; B 9, a portion of the same still more highly magnified; B 10, lines showing measured lengths of legs of the 1st, 2nd, 3rd, and 4th pairs, and of palpus, with those of the several joints.
[Plate XVI.], p. 211, fig. A.—Part of the nest of Nemesia Simoni (Camb.) taken at Bordeaux; A 1, N. Simoni (Camb.) from life, of the natural size; A 2, the same seen in spirits, the legs not represented; A 3, the same seen sideways and magnified; A 4, the eyes, magnified; A 5, the thoracic fovea, magnified; A 6, line showing measured length of spider, (see above explanation of fig. B 5, plate XV.); A 7, lines showing measured lengths of legs of the 1st, 2nd, 3rd, and 4th pairs, and palpus of spider, with those of the several joints. B, cephalothorax and abdomen of another specimen of N. Simoni, in which the proportions are different, taken from life, of the natural size.
[Plate XVII.], p. 215, fig. A.—Part of the nest of N. suffusa (Camb.) taken at Montpellier; A 1, N. suffusa (Camb.) from life, of the natural size; A 2, the same in spirits, seen sideways and magnified, the legs not represented; A 3, another view of the same; A 4, the eyes, magnified; A 5, length of spider (see above, fig. B 5, plate XV.); A 6, measurements of legs and palpus; B, N. meridionalis (Costa and Sim.), male, from a specimen in spirits, of the natural size, legs not represented; B 1, the same magnified; B 2, the eyes, magnified; B 3, radial and digital joints of the left palpus with bulb, magnified; B 4, another view of the same, magnified; B 5, back view of the same, magnified, but less highly; B 6, length of spider (see above, fig. B 5, plate XV.); C, N. meridionalis (Costa and Sim.) female, from a specimen in spirit of wine, of the natural size, legs not represented; C 1, eyes of the same, magnified; C 2, length of spider. These two specimens (male and female) were collected in Corsica, and named by M. E. Simon, who kindly presented them to me; they are now in the possession of the Rev. O. Pickard-Cambridge.
[Plate XVIII.], p. 225, fig. A.—Part of nest of N. congener (Camb.) taken at Hyères; A 1, lower door of this nest viewed from above, of the natural size; A 2, side view of the same; A 3, N. congener (Camb.) taken from life, of the natural size; A 4, side view of the same, enlarged to twice the natural size, the legs not represented; A 5, cephalothorax and falces from specimen in spirits, magnified;[108] A 6, the eyes, magnified; A 7, femur, patella (or genual joint) and tibia of leg of third pair, showing the three spines on the outer side of the patella, magnified. B, lower door from a smaller and younger nest, viewed from above, of the natural size; B 1, the same viewed sideways.
