NO. 10 CALDWELL: SOUTHERN CARIBBEAN FISHES 7 



Remarks: Although they appeared to be of this genus and species, 

 we questioned the determination of these specimens on the basis of recent 

 work by Rivas (1950: 277). He noted that there are always more than 

 32 ventral scutes in this genus, although Meek and Hildebrand (1923: 

 181) listed 25 to 35. We found 27 to 32 in a sample from our material. 



The anal fin ray count in material from this lot ranged from 15 

 to 17. We found 83 and 89 lower-limb gill rakers in stained material 

 from two specimens. One specimen so examined had 45 vertebrae, and 

 its depth was 4.5 in standard length and its head 3.4 in standard length. 



Engraulidae 



Material in this family was determined with the aid of Hildebrand 

 (1943). 



Anchoa cubana (Poey) ? 



Material: A 39-39, 10 (46.1—53.4 mm.), AHF 2317, from Rockly 

 Bay, Tobago Island, West Indies. 



Remarks: This material keyed out in Hildebrand to this species, 

 but it did not fit his description well ; possibly this was due to the poor 

 condition of the specimens. 



Four examples had 15 dorsal fin rays and 20 to 23 anal. One 

 specimen had 12 pectoral fin rays, three had 13, two had 14 and three 

 had 15. Six individuals had 15 to 19 upper-limb gill rakers, and eight 

 had 20 to 29 lower-limb gill rakers. The depth in standard length of 

 three specimens ranged only from 5.8 to 5.9. 



Anchoa ginsburgi Hildebrand ? 



Material: A 6-39, 14 (26.7—63.5 mm.), AHF 2634, from Caledonia 

 Bay, Panama. 

 Remarks: Six specimens had 15 to 16 dorsal fin rays and 19 to 22 

 anal. The pectoral fin ray counts of three examples ranged only from 



14 to 15. The upper-limb gill raker counts of six specimens ranged from 



15 to 17, and the lower-limb counts of seven ranged from 19 to 20. 

 The depth in standard length of three individuals ranged from 5.4 to 

 5.7. The axillary scale in our material was somewhat longer than 

 Hildebrand indicated for this species.
