^Pteroplatea crebripunctaia Peters, Monatsber, Berl. Akad, 1869, 703. This specie-s 

 is very common in the Gulf of California. It is thus described by Dr. Peters: • 



Breadth of disk twice the distance from tip of snout to vent. Snout with a blunt 

 projection ; anterior margin of pectorals undulate, convex anteriorly and posteriorly, 

 medially weakly concave ; outer angle sharply rounded ; posterior margins weakly 

 convex, the posterior angle rounded, covering outer half of base of ventrals ; spiracle 

 without tentacle ; tail fmntilated) with a low fold on its upper edge. Brown above, 

 with thick-set black points ; a row of small, close-set yellow spots on front ofdisk ; 

 under side yellowish. 



I have compared specimens of this species with P. maclura and P. marmoi'ata, and 

 regard the three as unquestionably distinct, although closely related.
