40 ALLAN HANCOCK ATLANTIC EXPEDITION REPORT 



Order HaPLODOGI 



Batrachoididae 



Batrachoides surinamensis (Bloch and Schneider) ? 



Material: A 35-39, 1 (51.0 mm.), AHF 2767, from Port of Spain, 

 Trinidad Island, West Indies. 



Remarks : We questioned our determination because we found but 

 one subopercular spine instead of the two indicated for this species by 

 Meek and Hildebrand ( 1928 : 915). The lack of a second spine may be 

 due to individual variation as yet undescribed, to age (our specimen was 

 much smaller than those Meek and Hildebrand described), or to anomaly. 

 In other respects our specimen satisfactorily fit the descriptions of this 

 species given by Meek and Hildebrand and by Jordan and Evermann 

 (1898: 2314). 



Although in color it superficially resembled the genus Opsanus, our 

 specimen clearly lacked the axillary pore of this genus that was noted 

 by Schultz and Reid (1937) or the ridged axillary structure of the closely 

 related genus Ainphichthys noted by Walters and Robins (1961: 13) 

 and illustrated by Breder (1925: fig. 1). 



Nautopaedium porosissimum (Valenciennes) 



Material: A 53-39, 1 (18.1 mm.), AHF 2314, from Caledonia Bay, 

 Panama. 

 A 18-39, 1 (88.0 mm.), AHF 2313, from 8 mi. S. W. of 

 San Nicolaas Bay, Aruba Island, Netherlands West 

 Indies. 

 Remarks: This material was determined with the aid of Hubbs 

 and Schultz (1939). 



Porichthys pauciradiatus Caldwell and Caldwell 



Material: A 7-39, 1 (33.9 mm.), AHF 3037 (Holotype), from 

 Caledonia Bay, Panama. 

 A 7-39, 6 (18.4—34.3 mm.), AHF 2766 (Paratypes), from 

 Caledonia Bay, Panama. 

 Remarks: This species was described by Caldwell and Caldwell 

 (1963) on the basis of this material. Considerable assistance in deter- 

 mining the material as new was obtained by consulting Hubbs and 

 Schultz (1939).
