CALDWELL ET AL.: CETACEANS OF ST. VINCENT 



ilton, 1945). S. fuscus Gray, from an un- 

 stated area in Cuban waters, may be this species 

 (True, 1889: 27) and if so would represent 

 another Cuban record. However, the unique 

 type of this latter species, a preserved fetus, 

 apparently was lost even in True's time and the 

 record cannot be substantiated. Presumably the 

 previous Caribbean records of this species (see 

 above) have been based on this Cuban material. 



Tiirsiops truiicatus (MONTAGU) — 

 BOTTLENOSED DOLPHIN 



The Caldwells have color ijhotographs of the 

 head of an immature specimen of unknown size 

 and sex taken in the fishery on 17 May 1968. 

 The head was obtained from a market where 

 it had been split longitudinally in order to get 

 to the brains, which are eaten. The skull (SV- 

 1-TT) is also split but comjilete. 



This species has not been reported from St. 

 Vincent before, but Turner (1912: 13.5) listed 

 the mandible (as Turslops tursio) of a speci- 

 men from nearby Barbados. 



Grampus grhet/s (G. CUVIER) — 

 RISSOS DOLPHIN OR GRAY GRAMPUS 



The Caldwells have the skull (SV-l-GG) and 

 color ijhotographs of the intact head of a speci- 

 men of unknown size and sex taken in the fish- 

 ery in the summer of 1968. They also have 

 the skulls of two more specimens (SV-2-GG, 

 SV-3-GG) , of unknown size and sex, taken dur- 

 ing the summer of 1970. 



In addition, the Caldwells have black and 

 white photographs (SV-4-GG) of an individual 

 (also of unknown size and sex) taken in Sep- 

 tember or October 1967. 



Until recently this species was considered a 

 northern foi'm in the western Atlantic, but 

 specimens are now available from Florida (Paul, 

 1968) and there is a recent sight record from 

 the Virgin Islands (Erdman, 1970). The rec- 

 ords from St. Vincent seem to be the mo-st south- 

 ern in the western Atlantic, and the only West 

 Indian ones supported by specimens. Mention 

 of this species in the St. Vincent fishery was 

 made by Caldwell and Caldwell (in press). 



Stenella, SPECIES A— LONG-SNOUTED 

 OR SPINNER DOLPHIN 



The Caldwells have color photographs of the 

 head of a specimen of unknown size and sex 

 taken in the fishery on 17 May 1968. The skull 

 (SV-l-SL) was saved but is split longitudinally 

 (see Tursiops account above). 



The Caldwells measured three females (177.0 

 [SV-2-SL], 166.5 [SV-3-SL] and 1.50.0 [SV-4- 

 SL] cm from tip of upper jaw to fluke notch) 

 which were taken on 24 May 1968. They have 

 black and white photographs (Figure 1) of the 

 middle-sized animal taken from several angles, 

 and the skulls of the two largest. 



There is confusion in the literature regarding 

 the systematics of the long-snouted spinning 

 dolphins of the genus Stenella, and the group 

 is badly in need of revision. The St. Vincent 

 dolphins clearly spin, as observed by all of us 

 at sea off the island, and our specimens (ex- 

 ternally) and their skulls compare favorably 

 with those reported from the northern Gulf of 

 Mexico as S. longhvstris (Gray) by Layne 

 (1965), but neither we nor Layne made similar 

 comparisons with S. roseiventris (Wagner) 

 which Rice and Scheflfer (1968) retained as a 

 species separate from 5. loiigirostris although 

 many writers consider them to be synonyms. 

 For the present we do not apply a specific name 

 to our material but note only that the specimens 

 from St. Vincent appear to belong to the "long- 

 iwstris-roseiventris" group of Stenella. 



The closest western Atlantic records for dol- 

 phins of this type are from the Bahamas near 

 Miami. Fla., to the north (Moore, 1953) and 

 (as Delphinus micivps) from Brazil (no local- 

 ity) to the south (Gray, 18.50: 126). 



Stenella, SPECIES B— SPOTTED OR 

 BRIDLED DOLPHIN 



The Caldwells measured a 172.5-cm male 

 taken in the fishery on 24 May 1968, and have 

 black and white ])hotographs (Figure 2) taken 

 from several angles and the skull (SV-l-SF). 

 The photographs, taken under adverse lighting 

 conditions, do not show the spotted ])igmenta- 

 tion pattern of the specimen because in addition
