1941 CATALOGUE OF FISHES OF TORTUGAS 65 



185 mm. long, are commented upon by Dr. Longley as follows: "Believed to 

 have come from floating Sargassum. In the female a keel on dorsal surface of 

 snout from tip to level of posterior nostril, where it bifurcates and continues into 

 the interorbital space, finely serrate throughout its length. In the male the keel is 

 simple throughout its length from tip of snout to interorbital space, and is ser- 

 rated only from the anterior end to nostrils. Supraorbital keels similarly serrulate 

 and converge posteriorly on crown. A very slight unserrated keel upon the 

 opercle, with ventral and posterior radiating striae. A nuchal serrated keel. Rings 

 in female 20 + 36; D. 34, on 3 + 5 rings. Rings in male 19 + 37; D. 37, on 4 + 

 5 rings; brood pouch on 19 rings." 



Two additional specimens, one of them a very large male, 277 mm. long, have 

 the following proportions and counts: Head 7.7 to 8.5; depth 27 to 32; base of 

 dorsal 8.5 to 9.2. Eye in head 8.6 to 9.1 ; snout 1.7 to 1.8; depth 3.7 to 4.5; base of 

 dorsal 1.0 to 1.2. D. 33, 34, on 2% ~\~ 5, 3/4 +4 rings ; rings 20 + 33, 22 + 34; 

 brood pouch on 17 rings. 



This species of the South Atlantic and Gulf coasts is now recorded from 

 Tortugas for the first time. S. F. H.

The synonymy as given is mostly from Dr. Longley 's report in Carnegie Insti- 

 tution of Washington Year Boo\ No. 32, 1933, page 293. With much of it Gins- 

 burg, who recently revised the genus (see citation above), is in agreement. 

 Ginsburg, however, recognized punctulatus as only a subspecies of hudsonius. 

 He similarly recognized kjncaidi, but considers brunneus synonymous with 

 kjncaidi. 



The 32 specimens in the collection all appear to be Hippocampus punctulatus, 

 according to Dr. Longley, or H. hudsonius punctulatus according to Ginsburg. 

 Much individual variation with respect to depth of body, prominence of tubercles, 

 presence or absence and length of fleshy filaments, and color is evident. Accord- 

 ing to Ginsburg this subspecies in general is rather deeper, has a rather longer 

 snout, and has more numerous white dots than the other subspecies, hudsonius 

 and \incaidi. 



Dr. Longley mentioned 21 catches in his notes, indicating that the sea horse is 

 fairly common at Tortugas. Specimens were taken in turtle grass and with an
