By GEORGE S. MYERS, Stanford University, and EARL D. REID 

 United States National Museum 



Among the fishes obtained by Dr. Waldo L. Schmitt, Curator of 

 Marine Invertebrates in the United States National Museum, during 

 the 1935 cruise of Capt, .G. Allan Hancock's yacht Velero III, we 

 find a most interesting new species of the genus Acantheryiblemaria. 

 The three hitherto-known species of the genus are all West Indian 

 (Metzelaar, 1919, p. 159; Beebe and Tee-Van, 1928, pp. 244-249).

Holotype. — U.S.N.M. 102015, a specimen 31.8 mm. in standard

 westernmost island of the Secas Islands, Pacific coast of Western 

 Panama. Hancock Pacific Expedition, 1935. 



Paratypes. — U.S.N.M. 102016, two specimens 30.8 and 31 mm. in 

 standard length; same data as holotype.

 bulging on each side, but upper profile of head continuously decurved 

 from dorsal fin to snout tip. Head 3.7 to 3.9 in standard length, 

 depth 5.8 to 6.1, predorsal distance 5 to 5.2, preanal distance 2.3 to 

 2.5. Pectoral 1.2 in head length (measured to upper angle of gill 

 opening), pelvics 2.3, caudal 1.5, snout 7.7 to 7.9, interorbital 6.4
