similar ridge with or without median notch but not divided as 2 dis- 

 tinct processes; free edge of nasal flap with distinct median projec- 

 tion; interorbital 3 in head to hind spiracle edge. Spiracle large, 

 equals interspiracular space. 



First dorsal inserted entirely behind ventral, length 2 in head 

 measured to hind spiracle edge; second subequal with first, inter- 

 dorsal space about 1% in second dorsal length; caudal IV3 in head 

 to hind spiracle edge ; pectorals form slightly ovate disk, about wide 

 as long ; ventral about I/3 pectoral length. 



Above warm chocolate brown, without spots, under surface creamy 

 white. Narrow cream white edge around disk, more distinct anter- 

 iorly. Dorsals and caudals edged gray white. Length, 220 mm.

India. Narcine flrma is based on an example 432 mm., with "colors 

 too faded for description," and would appear to represent advanced 

 age. The characters Garman gives, such as the first dorsal having its 

 basal length behind ventral bases, caudal obliquely rounded, and 

 rostral ridges nearly parallel, do not seem to me sufficient.

Disk less than half total length, broad, subovate, nearly round, 

 slightly narrowed and edges straighter opposite head, wider than 

 long. Snout strong, broadly rounded in front; eyes small; mouth 

 protractile; teeth bands moderate, semicircular on outer edges; teeth 

 in 25 rows in each jaw, small, each with prominent acuminate cusp 

 on inner edge of crown; front nasal valves confluent in broad flap, 

 free on hind edge, reaching teeth in rounded prominence, angles 

 rounded; hind nasal valves quite rudimentary, absent around un- 

 covered portion of nostril, slightly developed in thin fold back from 

 middle of nostril toward mouth angles; crown convex transversely. 

 Spiracles larger than eyes, close behind orbit, with rudimentary 

 papillae on margins. 



Dorsals subequal, rather pointed, bases wider than fins ; first dorsal 

 origin little behind ends of ventral bases, space from second more 

 than half of base ; caudal longer than deep, vertically truncate.
