1891.] TADPOLES OF THE EUROPEAN BATUACHIANS. 6l7 



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 (Recli. Osteol. Myol. Batr. 1835, pi. xiii. fig, SO, 

 and pi. add. fig. 8), Des Moulins (Actes Soc. Linn. Bord. xxix. 18/4, 

 pi. vi.), and Lataste (Actes Soc. Linn. Bord. xxx. 18/6, 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.

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 back- 

 wards, 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 tliree 

 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,

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 in- 

 distinct. 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 Hues, 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 bifur- 

 cated 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 hue on the flanks, curved above the spiracuhim, not bent
