NO. 9 AMERICAN FISHES IIILDEBRAND 3 



dorsal fins 3.7 ; upper part of caudal fin with a rather acute angle, 

 lower part rounded, the rest of margin nearly straight ; ventral with 

 nearly straight distal margin, its outer margin 3.7 in length anterior 

 to vent; clasper fully a third longer than adjacent part of ventral, 

 T,.2 in length anterior to vent. 



Color brownish above, with many indistinct dark spots : plain pale 

 underneath. 



The description ofTered herewith is based on the holotype, the (july 

 specimen known, a male 212 mm. long, taken by Waldo L. Schmitt. 

 for whom this species is named, at White Friars Island, off the mouth 

 of the Gulf of California, dredged in 5 to 10 fathoms, on March 3, 

 1934 (U.S.N.M.Xo. 94044). 



This species is related to A\ oitciiicdor Jordan and Starks and 

 .V. vcrmiciilatus Breder. From the first it differs prominently in the 

 much more robust tail, which is deeper and less strongly depressed, 

 and from the second (of which I have seen no specimens) it seems 

 t(i differ, according to the published accounts, in having smaller 

 spiracles, which are about equal in size to the eyes, and not notably 

 larger as in vermiciilatus. It differs from both species in color, as the 

 upper surface is marked with indistinct dark spots, whereas adults of 

 cntemcdor are of a uniform gray, and vcrmicnlatus has pale markings. 



This species, like venniculatus, seems to become sexually mature 

 at a smaller size than entemedor, as the claspers in the 212-mm. male 

 are much longer than the adjacent parts of the ventrals, and apparently 

 fully mature. In a male cntCDicdor 215 mm. long they are equal in 

 length to the adjacent parts of the ventral.-, and are thin, fiexible. and 

 apparently immature.
