\ long-, narrow, the jiillar and body with a moderate calhis; pillar and 

 1^ canal short, hardly recurved; outer lip tumid, coarsely lirate within. 

 Lon. 9, lat. 4.5 mm. 



Oligocene of the Isthmus of Darieii, near Gatun, llowell, Hill, and 

 others. No. 113713, U.S.N.M. This little shell has the aspect of an 

 Astyris, but the aperture of a Stromhina. It may be mentioned here 

 that the Planaxis erassilabrnm of Guppy,from the Tertiary of Trinidad, 

 is founded, according to the types, on defective specimens of a IStrom- 

 hina, which is probably iS. haitensis, Gabb. 



TYPHIS, doubtful species. 



Ditrupa bed, Pointapier, Trinidad, Guppy (213G). No. 10713G, 

 U.S.N.AI. This species, represented by an extremely small immature 

 specimen, was referred by Mr. Guppy to T. al/ttus, Sowerby, but a 

 careful examiuation of it shows that it is more nearly related to T. lingui- 

 ferus, Dall, of the Chipola, Florida, Oligocene and to T. reciirvirostratus. 

 Until a more mature specimen is obtained it would be inadvisable to 

 apply a specific name to this species. 



TYPHIS OBESUS, Gabb. 

 Ti/phis ohesus, Gabb, (Jeol. Santo Domiugo, 1873, p. 203. 



Oligocene of Santo Domingo, Gabb; of Jamaica, Vendryes and Hill; 

 of the Chii)ola marl, Calhoun County, Florida, Dall and Burns. Nos. 

 1154JI4, 112182, and 107455, U.S.N.M. This species was collected in 

 Jamaica by Vcndrycs and named T. nlatns in the Guppy collection, 

 but it appears to be a sufficiently distinct species from Sowerby's shell 

 and much more common. It is also found, rarely, in the Chipola marl. 



A third si)ecies of Typhis from Jamaica is represented in the collec- 

 tion of the N^ational Museum by a single, not very well preserved, 

 specimen. It is closely related to, if not identical with, T. fforidanus, 

 Dall, of the Chipola marl. 



In this connection the following notes on si)ecies cited in Mr. Guppy's 

 catalogue of West Indian Tertiary fossils may not be out of place: 

 Trophon dominicensis, Gabb, is a well-marked species of Jifurex, from 

 which Miirex eollafKS, Guppy, is perfectly distinct. Purpura mioccriica, 

 Guppy, is a CoralUophila, probably identical with a species now exist- 

 ing and commonly known as C. galea^ Chemnitz. Fasviolaria tarhelliana, 

 Grateloup, is a sjiecies of Latinis. 



ACLIS ACUMINATA, Guppy, new species. 

 (Plate XXVIII, fig. 9.) 



Elongate-turrited, smooth, shining; whorls about 9, slightly convex; 

 suture well marked, overhung by the whorl above; aperture subquad- 

 rate; columella lip reflected. Alt. 3, lat. 0.5 mm. [G.J
