REVIEW OF HIPPOCAMPUS — GINSBURG 565 



Geographic distribution. — It was suggested (p. 559) that the geo- 

 graphical Umits of the State of Florida be arbitrarily considered as the 

 northern geographical limit of pundulatus. The specimens examined 

 from Florida represent the range from Biscayne Bay to Pensacola. 

 South of Florida specimens were examined from Cuba. This must 

 stand for the present as the known range of punctulatus, and its precise 

 distribution remains to be determined ; but in any case its geographical 

 limits on the coast of the United States will have to be arbitrary. 



Whether the seahorses from islands adjacent to Florida and Cuba 

 are referable to punctulatus or to some other species or subspecies 

 remains to be learned. Kecords in the literature of "punctulatus" 

 from other West Indian islands or the coast of South and Central 

 America appear doubtful or are evidently erroneous. On account of 

 the general failure of authors to discriminate properly between the 

 species of Hippocampus, it is not possible to state to which species a 

 given record belongs unless the specimens on which the record is based 

 are reexamined. 



Material studied. — Biscayne Bay, Fla; December 5, 1902; H. F. 

 Moore (67596). Key West, Fla. (89786, Pinchot expedition, April 

 10, 1929, and 38689, Albatross, January 14, 1885; also, a very smaU 

 specimen in Bureau of Fisheries collection, June 10, 1919). Off 

 southern Florida; lat. 26°19' N., long. 83°33' W.; March 18, 1889, 

 Grampus (43579). Captiva Pass, Fla.; O. P. Hay (Field Mus. Nat. 

 Hist. no. 32829). Tampa Bay, Fla.; Fish Hawk (49714; 49715; 

 49716; 49717). Port Tampa; January 19, 1898; Fish Hawk (84598). 

 Tarpon Springs, Fla. (93753, D. Mehsas, April 11, 1930; also one 

 specimen in Bureau of Fisheries, Evermann and Kendall, November

 AprO 3, 1887; J. F. Mosher (39361). Cedar Keys, Fla. (86117, C. R. 

 Aschmeier; 22213; the two larger specimens in the last bottle ap- 

 parently belong to hudsonius and may have been added later, since 

 the register records only one specimen for that number). Pepperfish 

 Key, Fish Hawk (73240). Apalachicola Bay, Fla.; shrimp trawl; 

 June 22, 1932; collected by the author. Off Cape San Bias, Fla.;

 stylijer; 30788, S. Stearns). Cuba, near western end, obtained by 

 Tomas Barrera expedition in 1914, as follows: Cape Cajon, submarine 

 light, May 26 (82386); Punta Colorado, submarine hght. May 21 

 (82385); Ensenada Santa Rosia, 23 mm, dredged in 1-3 fathoms. 

 May 18 (82388); Esperanza (82387).
