slightly converging. Tongue small, ova 1 , free posteriorly and laterally. Paro- 

 tids present, porous. Digits 4 5. Tail long, compressed.

4. Bradybates (Tschudi.) Palatine teeth few. Tongue small, round, at- 

 tached by its whole inferior surface. Extremities short, small ; digits 4 5. 

 Body depressed, no parotids. Tail short, broad at base, subcylindrical. 



B. ventricosus (Tsch.) 



III. Tritones. 

 Palatine processes cuneiform. Ribs not developed. Habits aquatic, many 

 species furnished in the breeding season with dorsal crests, and interdigital 

 membranes. 



5. Glossoliga (Bp.) Longitudinal series of palatine teeth in two widely 

 separated rows, slightly converging anteriorly. A strong postorbitar arch, 

 formed by the union of a process of the posterior frontal with that of the tym- 

 panic bone. Maxillary bone uniting immediately with the pterygoids. Tongue 

 rounded, free posteriorly and laterally. Digits 4 5. Tail moderate, some- 

 what compressed. 



A remarkable genus, quite distinct in many points of structure from 

 Euproctus, with which Dum. & Bibron unite it. 

 G. Poire ti (Gervais.) 



6. Diemyctylus (Rafinesque.) Longitudinal series of palatine teeth in two 

 straight rows, closely approximated anteriorly, widely diverging posteriorly. 

 A strong long arch above and behind the orbit formed by the united processes 

 of the posterior frontal and tympanic bones. Tongue small, thick, oval, at- 

 tached by its whole inferior surface or with a very slightly free lateral border. 

 Digits 4 5, the exterior and interior upon the hind feet rudimentary. Tail 

 moderate, compressed. 



Syn. Diemyctylus Rafinesque, 1820. JVotopthalmus Raf., 1820. Cynops Tsch. 

 1838. Taricka Gray, 1850. 



We regret that the law of priority compels us to employ Rafinesque's objec- 

 tionable name in preference to Cynops Tschudi or Taricka Gray. We prefer 

 Diemyctylus, though apparently unmeaning, to the egregiously inappropriate 

 JVotopthalmus of the same date. 



D. torosus. Triton torosus Esch. Zool. At. pt. v. pi. 21. fig. 15, 1833. 

 Triton Ermarmi Weigmann, 1835. Triton granulosus Skilton, 1849. Taricha toro- 

 sus Gray, Cat. Brit. Mus., 1850. 



The external characters of this animal present no peculiarity that appears to 

 us to warrant generic separation from the succeeding species.

This species in the development of the temporal region exhibits characters 

 most typical of the genus. We fail to perceive the generic difference admitted 

 by authors to exist between this and the following species.

We include in the above synonymes those of the nominal species D. 

 miniatus, which we think with Dr. Hallowell (Proc. Acad. Nat. Sci. Feb. 

 1856) is a state of D. viridescens. We have caught specimens with or
