The para sphenoidal portion of the roof of the mouth is much re- 

 stricted laterally and behind. 



The body is full, rounded, and depressed. There are eleven costal fur- 

 rows, including inguinal and axillary. 



The tail is compressed, but oval in cross-section, with the lower edge 

 rather sharj) towards the end. The upper outline is much rounded. It 

 is not high, and not as long as the rest of head and body ; longer than 

 from snout to groin. In one specimen there is a distinct furrow along 

 the under side. 



The limbs are large; the digits lengthened; more depressed than in 

 A. punctatum, but linear, not triangular in shape. The lateral ones are 

 more lengthened than usual, and those of each limb are more nearly of 

 a length. The free portion of longest finger is more than one-third 

 from tip to elbow; that of longest toe in the same proportion. 



The gai^e of the head is wide; the length more than half the width. 

 The width of the head is contained four times in distance from snout to 

 groin.

The color in one specimen is everywhere a dull reddisli-olive or 

 brown, paler beneath, and without the trace of any spots. No. 4707 is 

 much darker, nearly black. 



The Amhlystoma trisrupUim Cope, from Ocate Creek, is similar to the 

 present species in the intervals between the four palatine patches and 

 the glands on the parotid region. The rest of the skin, however, as far 

 as can be ascertained, is glandular, as in A.punctatum, tigrinunij etc. The 

 digits, too, are shorter, flatter, more triangular, the lateral and central 

 more unequal. The eyes are much smaller and farther apart. There 

 are twelve costal furrows, not eleven, etc.
