 Spelerpes multiplicatus, Cope, Proc. Ac. Philad. 1869, p. 106. 



Palatine teeth forming short series, each rather suddenly bent 

 backwards, not extending outwards beyond choanae, well separated 

 from parasphenoid patches ; latter separated. General proportions 

 as in Batrachoseps scutatus. Head flat; snout rather thick and 

 short. Fingers and toes free, short, especially inner and outer. Tail 

 a little compressed and considerably thickened, keeled at the end. 

 Twenty-one costal grooves. Brown, inferior surfaces paler ; some- 

 times the brown colour forms a broad dorsal band with dark points ; 

 the sides are of a pinkish grey, and the under surfaces light yellow. 

 Total length 82 millim.

Series of palatine teeth arched, not extending outwards beyond 

 the choanee, separated from parasphenoid patches ; latter separated. 

 Head moderate ; snout truncate. Body moderately elongate, mea- 

 suring not quite three times the distance from snout to gular fold. 

 Limbs moderate ; fingers and toes short, free ; a prominent wing- 

 like rudiment only of the inner digit on both pairs of extremities. 

 Tail cylindrical, slightly longer than head and body. Skin smooth ; 

 a distinct gular fold; eleven (or twelve) costal grooves. Dark 

 brown above, with or without a reddish or yellow dorsal band ; 

 sometimes uniform black. The single specimen at my disposal 

 is dark brown above, with two yellow dorsal bands, narrower 

 than the space between them, commencing on the parotoid region, 

 uniting and continuing on the taU ; the lower surfaces light brown. 

 Head and body 24 millim. ; tail 26 millim.

The shortest and stoutest species of the genus, the form being more 

 that of AmbJystoma opacum. Series of palatine teeth nearly straight, 

 not in contact, externally extending beyond choansB, separated from
