Description. — This species is closely allied to E. albescens, from 

 which it not only differs in having a smaller number of laminae (which 

 I do not think very important), but also a shorter mouth and a 

 shorter ventral fin. The disk is elliptical, rather broader posteriorly 

 than anteriorly, and 1| as long as broad; its length is 3} in the 

 total, and it extends not quite so far backwards as the pectoral ; the 

 membranaceous margin is rather broad and depressed. The mouth 

 is broad and truncated ; its cleft extends laterally to the vertical 

 from the posterior nostril, or from the second lamina of the disk. 

 The jaws, the vomer, the palatine bones, and the tongue are armed 

 with bands of villiform teeth ; the lower jaw and the vomer have, 

 besides, an outer series of stronger teeth, which are rather widely 

 set. The eye is small. 



The length of tlio head is 4| in the total, the widtli of tlie body 

 between the pectorals five times. 'J'he back bcliind the head is very
