costal fiiiTows, oxd^l(lin^' an axillary oiic, and livo pelvic. Similar fur- 

 rows ran In- traced to the tip of the tail. Tlie tail is (juadrate at the 

 base, with ronnded anj-les, broailer than hi-;'!!, but becomes more and 

 more compressed to the tip. The limbs are feeble and widely separated. 

 The di^'its all distinct, but small ; the lirst rather riidinicntary. 



In alcohol mature individuals of smaller size are of a lij;hl brownish- 

 red on the baitU, the sides and itenealh pile reddish salmon t'olor. The 

 sides of body and tail, however, and to a less extent the back, are closely 

 covered by a coarse, indistinct reti(!uIation or network ol" rather dark 

 brown, showinj? the li;.jliter -iionnd color in tlu^ areola', and <!onvcyin<,' 

 the impression of rathei- oblon.i- lij;hl spots. Tlie under parts are 

 jjenerally immaculate, tliou.;;h larjic spiMtimens are sometimes fiindy 

 sprinkled with dusky. There is always a li<;ht line from the eye alonj^- 

 the can thus to thecdj-e of t!ie upper Jaw; those of opposite sides parallel. 

 With iiicreasin;;' aji'e liie icticulation of the. sides be(!onu's obscured 

 by theextension of the ^rouml color of tlu^ i)a('k over the sides and Jie 

 •fading (tut of tlu! dark markinjjs. Tlier<' is, however, j,M>nerally a dull 

 (iloudiuH' (»f darker and a. faint indiiiation (»f the light spots, especially 

 on the lower part of the sides. 



This species dilfers from tSiKlrrpiH nihcr in many details of external 

 fiU'iii — the more vermifoiin and depresse<l body; inoi'e widely separateil 

 fore and hind legs; oiu> more costal furrctw ; the more depressed, nu)r(^ 

 truncate, and broader head; larger eyes; prominent ridge iVoin eye eon- 

 tinned to margin of upper Jaw. etc., not to nuMition the diU'creniie in 

 coloration. To S. r. Jhirissiiii lis it is related l»y the |Motuberan(U's on 

 the upper jaw on each side the muzzle, iuit these are less pi-onnnent. The 

 tifteen costal groovesandsiiai'ply detined idaek sp(»ts without reticulation 

 on the sides distinguish the former. 



A specimen from (Icoigia (I7l(i) dilfers in a more slender shape, and 

 in having dark, horny tips to the digits, as in tli<' afpiatic Audilystonue, 

 as if having lived in a drier region than usual. 'I'herc are only lifteen 

 costal grooves to be distinguished.
