The catch of 25 Membras martinica at station FF-1 

 in October is a subsample of 496 atherinids. The 

 remaining fish were discarded at sea and are not in- 

 cluded here.

Although we only took 16 holocentrids, and these 

 are not specifically identified, one comparison may be 

 made with the study of Holocentrus vexillarius by 

 McKenney (1959). McKenney caught specimens from 

 5.8 to 24.9 mm only at dusk or night. All our catches 

 were also made in periods of twilight or night, never 

 during the day. Evidently these nocturnal fishes begin 

 their avoidance of light at an early age. The depth to 

 which they descend during daylight is unknown.

The pipehorse, Amphelikturus dendriticus, is rarely 

 caught and is known only from the Bahamas and Ber- 

 muda (Bohlke and Chaplin 1968). The presence of the 

 young specimen in shelf waters off Florida indicates 

 that the Gulf Stream may affect to some extent the 

 dispersal of its progeny. 



The capture of the northern pipefish, Syngnathus 

 fuscus, at Cape Kennedy represents a range extension 

 of about 85 miles beyond its previously reported 

 southern limit at St. Augustine (Briggs 1958). 



Syngnathids were present the year-round in our 

 collections, but during the winter most occurrences 

 were restricted to waters with temperatures above 

 20°C. Syngnathus springeri, however, was caught 

 during the winter at temperatures as low as 10.4° C. 

 Evidently, this coastal species tolerates lower 

 temperatures than more pelagic species of pipefishes.

The short bigeye spawns from early July to mid- 

 September, at the latest (D. K. Caldwell 1962), and 

 drifts at the surface before metamorphosing and 

 assuming a demersal existence. The fact that we took 

 no specimens during the October cruise indicates that 

 the premetamorphic pelagic stage lasts less than 2 

 mo.

Because most meristic characters are shared by 

 western Atlantic apogonids, color patterns are impor- 

 tant in identifying species. The postlarva here iden- 

 tified as Apogon maculatus (Fig. 13) has acquired the 

 pattern characteristic of adults: a band of pigment 

 posterior to the eye and across the opercle, a spot on 

 the body under the second dorsal fin, and a saddle of 

 pigment on both sides and top of the caudal peduncle.
