This specimen has eleven gill-rakcrs on the h)\ver antericjr arch; 

 I). XII, 2(->: A. \'I. 2S; live rows of scales on the cheeks; forty-two 

 scales in the row below the lateral line; fourteen scales between the 

 first dorsal spine and the lateral line; thirty-three scales between the 

 origin of the \entrals and the lateral line; caudal peduncle about 

 half as long as deep; depth 11 in the length. In regard to the smaller 

 scales this specimen is somewhat like P. altutn, but in most of the 

 details it is within tlu- limits of P. scalare. 



Note. — As Mr. Haseman's account of the genus Helerogramma leaves the im- 

 pression that the species are scarcely distinguishable, I have had photographs 

 prepared of all the species mentioned except H. orlmanni, which is soon to be 

 figured (Memoirs Carnegie Museum, V, 1911, pi. — ). — Carl H. Eigenmann.
