AMBLYSTOMA TRISEUPTUM Cope. 

 Proceeds. Acail., Phila., 1867, j). 194. 



The species is stout aud heavy in build ; the head very broad and 

 much depressed. The skin is granulated by contraction of the alcohol, 

 but m respect to glands, pits, etc., appears much like other species. 

 There is, however, a decided feature in certain particles which crowd 

 the parotoid region, and are seen also on the top of the head along the 

 inner margin of the orbit, and perhaps below the eye. I have not 

 noticed this character in any other species east of the Eocky Mountains. 



The head is broad, ovate, rather pointed anteriorly. The inner and 

 outer nostrils are nearly the same distance apart. The tongue is broadeJ:" 

 than long, more than half the width of the head, filling the interspace 

 of the same anteriorly. 



The teeth are in four very distinct patches, with decided intervals. 

 They form one transverse series, nearly" straight centrally (where they 

 are in a line with the posterior border of the internal nares), but curving 

 slightly backwards laterally. The two central patches are wider than 

 the lateral, which vary a little in length and are separated by an inter- 

 val half the diameter of the inner nares. Their distance from the exte- 

 rior iiatches is about twice as great, the center of the interval falling 

 about opposite to the inner border of inner nares. The outer patches ex- 

 tend about half a diameter beyond the outer border of inner nares. 



The remaining external characters of the specimen are not different 

 from those of ^. tigrinum. 



The colors of the specimen are much obscured by bad preservation. 

 It appears to have been of a uniform dark blackish or bluish brown, with 

 a single series of large transversely elliptical blotches of yellow from 

 head to tip of tail, half on body and half on tail; the foremost one 

 rounded and placed behind the eyes. Those of opposite sides nearly 

 meet on the back, and are confluent on the upper edge of the tail. 



This is the only species I have seen of the group in which a strictly 

 transverse series of palatine teeth behind the eye is divided into four 

 groups. 



The only known specimen is the following : 



No. 4068 5 1 specimen ; Ocate Creek, New Mexico. 9 . 



Ocate Creek is on the eastern side of the Sangre de Cristo Mountains, 

 the southern part of the eastern range of the Kocky Mountains in New 

 Mexico.
