nearly smooth, except for incremental lines, while they rapidly become 

 more rounded; suture distinct; aperture with the outer lip somewhat 

 receding- in the middle; inner lip moderately callous; pillar half a turn 

 inside the apcj'ture showing a prominent basal keel ; canal twisted, with 

 a distinct fasciole. Diameter of spire at decollation, 2.75; maximum 

 diameter of twelfth subsequent whorl, 24; longitude of (decollate) 

 shell, 70 mm. 



Hahifat. — Older Miocene of Santo Domingo at the Potrero, lliver 

 Amina, Bland; Gabb, various localities on the same island. 



Types.— No. 113751, U. S. N. M.; and in the Academy of Natural 

 Sciences, Philadelphia. 



This species has hardly more in common with the Pacific T. robusfa, 

 Hinds, than the fact that the sculpture is obsolete on the later whorls. 

 It grows much larger than the dimensions given above, and the last 

 whorls become much swollen. 



TEREBRA HAITENSIS, new species. 



Shell slender, acute, all the whorls sculptured, the early whorls with 

 a double subsutural baud, as in the last species, but with the riblets 

 crossing the wider band vertically, becoming oblique on the anterior 

 band, where they are almost nodulous, and forming arched waves on 

 the rest of the whorl to the suture, but becoming suddenly obsolete 

 at about the line of revolution of the suture and thence over the base 

 to the canal; aperture rather short; pillar short, twisted, with a single 

 basal keel, which falls short of the aperture; canal short, sharply re- 

 curved ; spiral striation obsolete or none. In a specimen of 24 whorls, 

 excluding the nucleus, the total length is 02, the maximum diameter 

 11.5 mm. 



Habitat. — Older Miocene of Santo Domingo at the Potiero, River 

 Amina, Bland; Gabb, various localities on the same island. 



Type.— No. 113753, U. S. X. M. 



This species diiiers from the preceding by not losing its slender form, 

 by preserving its sculpture, by details of the sculpture, and by its more 

 numerous whorls in the same length. 



TEREBRA (HASTULA) INORNATA, new species. 



Shell small, slender, nearly smooth, without any sutural band or spiral 

 sculpture, and with about a dozen whorls ; early whorls with a few obso- 

 lete transverse riblets, other whorls with no sculpture except the some- 

 what irregular incremental lines; whorls rather flat, suture distinct, 

 closely appressed; aperture longer than wide; outer lip thin, nearly 

 straight, simple; pillar short, simple, twisted; the canal moderately 

 wide; base rounded, without a carina. Longitude, 18; maximum diam- 

 eter, 4 mm. 



Habitat. — Older Miocene of Shiloli, New Jersey, and St. Mary's 

 River, Maryland; collected by Burns and others. 



Types.— Nos. 100953-100955, U. S. N. M.
