I 



Dolophaaes melimoides, Gabb, is identical with Creintaoella cepula as 

 claimed by Mr. Guppy, and the latter name has priority. 



Iox)sis, Gabb, was founded on an immature Bissoina, as his type 

 specimen shows. 



ActKonidea, Gabb, is synonymous with Bictaxis, Dall, which has 

 two or three years priority. 



I have discussed Orthaulax, Gabb, in the Transactions of the Wagner 

 Free Institute of Science, Vol. III. The Petaloconchns of Mr. Guppy's 

 list is not P. sculpturatus, Lea, and should retain Sowerby's name of 

 domingensis. 



TurhoniUa suhcarinata, Orbigny, of Guppy's list, is an immature 

 Jiissoina, from Matura, Trinidad. 



Amauropsis ocalanus, Dall, from the Lower Oligocene of Florida, has 

 also been detected in Santo Domingo on the Eio Amina. 



Gryphcva athyroides, Guppy, has the aspect of an Ostrea, but the hinge 

 is inaccessible. 



Ccrcomya ledwformis, Guppy, is a Leda and, under the circumstances, 

 may better be renamed Leda (juppyi. 



Crassatella, labeled marylandica, Conrad, from the Oligocene of 

 Jamaica, is not that species, nor C.floridana, Dall, but probably an 

 undescribed species. 



Dosinia cycUca, Guppy, is a Lucinopsis. 



Corhnla vieta, Guppy, was founded on the sculptured valves of 

 6'. disjxtriliSj Orbigny; Erycina tensa, Guppy, upon the smooth valves 

 of the same species. 



Tellina, identified with T. hiplicata, Conrad, appears distinct, and 

 should retain d'Orbigny's specific name of sagra\ It belongs to the 

 subgenus Metis, H. and A. Adams. 



The following Polyzoa were included from the Jamaican Oligocene 

 and identified by Mr. Guppy: 



CUPULARIA OWENI, Lamarck. 

 MEMBRANIPORA SAVARTI, Audouin. 



There are several undetermined species of Polyzoa in the Ditrupa 

 beds of Pointapier, Trinidad. 



It may not be amiss to remark that Orbitoides mantelU lias been 

 repeatedly and persistently reported from the Tertiaries of the West 

 Indies; but in no case which I have been able to examine has the 

 West Indian species proved to be the true 0. mantelU. The most 

 southern locality for the genuine 0. mantelU is in the Guallava sand- 

 stones of Costa Eica, though the species doubtless occurs on the north- 

 western shores of Cuba. The West Indian form sent under the name 

 of O.manteUi'hiiSi been identified as O.forhesU, a much thicker, more 

 globose, and smaller species.
