22 "TERRA \<>V.\ EXPEDITION. 



Suoul twice as long as longitudinal diameter of eye with spiracle ; interorbita] width 

 equal to transverse diameter of eye. fnternasal width less than .', praeoral length of 

 snout, lfss than distance of either nostra] from edge of disc. Teeth obtuse, close-set ; 

 about 40 series m upper jaw, which has a median emargination. Disc smooth below, 

 above with scattered spines with radiating liases, set inure closely near the anterior 

 ami posterior margins : a. series of spines at inner margin of each orbit : a triangular 

 patch en scapulary region : tail with three series posteriorly, five anteriorly, continued 

 forward mi the disc as two only : two spines between the well-separated dorsal tins. 

 Brownish, with scattered darker and paler spots. 



A single specimen, a young female, 220 mm. in total length. In the spination 

 and in the separation of the dorsal tins tins species is nearer to the Chilean one 

 described by Garman from an adult male as Malacorhinn minis than to Psammobatis 

 nulla, Giinth. Malacorhinn seems to be a synonym of Psammobatis, and the adull male 

 ot Pa. cirnfcr may have the anterior margins of the disc notched as in Pa. minis; 

 similar differences in form due to sex and age are known in Raia fyllae, Liitken.
