ilia 5*4 lines. From end of mu#zle to groin 13 9 lines, 

 of tail 21 "1 lines. Length of hind limb 4'4 lines. 

 Habitat. Mexican Table Land, Dr. C. Sartorius. 



From groin to end 



Spelerpes 1 i n e o 1 u s. 



The species has the general form of Batrachoseps attenuatus, but, as 

 the number of digits is as in Spelerpes, I retain it for the present in that ge- 

 nus. Form very slender ; fourteen costal folds from femur to axilla, the first 

 at the femur. Muzzle short, rather thick, regularly rounded ; eye large, di- 

 ameter equals frontal width between middle supercilia, longer than length of 

 muzzle. A delicate linear supraoccipital crest on the cranium. Limbs very 

 small, each extending backwards or forwards over but two costal folds. Digits 

 obtuse, rudimental ; no web. Tail compressed, slightly flattened above and 

 below, two and a half times length of body. Head to axilla a little less than 

 half from axilla to groin.- A delicate postgular fold. Color, above and below, 

 uniform glossy black. 



Length from end^f muzzle to rictus oris 1*4 lines. Length from end of 

 muzzle to axilla S-SWines. Length from axilla to groin 8*2 lines. Length 

 from groin to end of tail 20 "4 lines. Length of anterior limb 1-2 lines. Length 

 of posterior limb 1-5 lines.

* The species from Natal, supposed by me toba R. mascariensis, from Natal, Pr. Acad. Phil., 

 1862, 340 is very different, and may be called it s p i n i d a c t y 1 a. 



t The so-called diacranterian and allied genus Stegonotus, D. B., has but a slight development of 

 the posterior tooth, and might be as well considered coryphodont. Giiuther's Lidaphis is identi- 

 cal.
