Show 1891.] TADPOLES OF THE EUROPEAN BATRACHIANS. 617 According to Duges, the size of the body may equal a hen's egg. The specimens from the Dep. He'rault, preserved in the British Museum, and for which I am indebted to the kindness of M . Heron Royer, are much smaller :-Total length 62 millim. : body 25, width of body 15 ; tail 37, depth of tail 12. Figures by Duges (Rech. Osteol. Myol. Batr. 1835, pi. xiii. fig. 80, and pi. add. fig. 8), Des Moulins (Actes Soc. Linn. Bord. xxix. 1874, pi. vi.), and Lataste (Actes Soc. Linn. Bord. xxx. 1876, pi. x. figs. 1-3, and xxxiii. 1879, p. 313). Inhabits the South of France, extending on the West coast as far north as the Loire-Inferieure, Spain, and Portugal. 14. PELODYTES PUNCTATUS, Daud. (Plate XL VII. figs. 1, 2.) Length of body rather more than once and a half its width, and not quite two thirds the length of the tail. Nostrils halfway between the end of the snout and the eyes, or a little nearer the latter. Eyes on the upper surface of the body, equidistant from the end of the snout and the spiraculum, the distance between them about twice as great as that between the nostrils, and equal to the width of the mouth. Spiraculum on the left side, directed upwards and backwards, nearly equidistant from either extremity of the body, visible from above and from below. Anal opening median, much larger than the opening of the spiraculum. Tail twice and a half to three times as long as deep, ending in an obtuse point ; the upper crest very convex, deeper than the lower, and rarely extending forwards as far as the level of the spiraculum ; the depth of the muscular portion, at its base, one third to two fifths of the greatest total depth. Beak white, with a black margin. An inverted fold at the side of the lip; this is furnished with a single row of papillae except on the upper border, which is toothed. Labial teeth in - or - series, x L 4 5 the second and third, both above and below, the longest; the first and second series in both divisions of the lip uninterrupted, or the second upper with very slight median interruption, the others separated iu the middle and gradually decreasing in length to the last, which, if present, is short. According to Bedriaga, there may be as many as six series of teeth on the lower lip, the first three of which are uninterrupted. Lines of crypts usually very apparent, but sometimes very indistinct. On the head they approach each other between the nostrils and completely border the eye posteriorly, the anterior extremities of this naso-orbital hoop approaching each other above the upper lip. Of the two dorsal lines, which diverge posteriorly, the upper, extending to the upper edge of the muscular portion of the tail, is interrupted at a short distance behind the eye ; its anterior portion may even descend to join the lower line, which thus appears bifurcated in front; the lower line extends, usually uninterrupted, from behind the eye to the middle of the muscular portion of the tail, where it is lost; both lines, however, may stop short of the tail. A sinuous line on the flanks, curved above the spiraculum, not bent |
