berg and Fischer have left little to criticise in the text, although we 

 could wish that they had assorted the new Pleitrotomidce into sub- 

 generic groups. H. A. P. 



DESCRIPTIONS OF TERTIARY FOSSILS FROM THE ANTILLLEAN 

 REGION, by R. J. Lechmere Guppy and Wm. H. Dall (Proc. U. 

 S. Nat. Museum, XIX, pages 303-331, Plates XXVII-XXX, 

 1896). In the preliminary remarks Dr. Dall gives stratigraphically 

 the source of the various fossils described. The Pliocene material 

 was obtained from Moen, Costa Rica. TheCaroui beds of Trinidad, 

 the deposits at Bowden, Jamaica, and in Haiti, and the Chipola 

 beds of Florida which have long been referred to the Miocene, are 

 here placed in the Upper Oligocene, no strictly Miocene strata be- 

 ing recognized in the Antillean region. The Gatuu beds of Con- 

 rad and Hill on the Panama Isthmus are Eocene, and contain a 

 fair proportion of the species common to the Claibornian of Ala. 

 and the Upper Tejon of Cal. " The list of Tertiary fossils of the 

 West Indian region, prepared by Mr. Guppy in 1874, comprised 

 some 250 species of fossil mollusks, but the fauna is much richer 

 than this, since in one day at the Bowden beds, Messrs. Henderson 

 and Simpson procured over 400 species. A significant proportion 

 of these appear to have survived little changed, or to be represented 

 by closely analogous species in the recent fauna of the West Indies." 

 In this paper 43 new species are described by Mr. Guppy and 19 

 by Dr. Dall, besides notes on a number of well known and doubtful 

 species. C. W. J. 



ON THE Grasius REMONDIA GAHB, A CROUP OF CRETACEOUS 

 BIVALVE MOLLUSKS, by Timothy W. Stanton (Proc. U. S. Nat. 

 Miis., XIX, pages 299-30], pi. XXVI). The type of this genus is 

 Remondia furcata Gabb. " The genus has been recognized in the 

 Manuals of Couchology and Paleontology, and placed in the Tri- 

 goniidte by Tryon, Zittel and Fischer, though the latter remarks 

 that it would perhaps be better placed near Axtnrte." Mr. Stanton 

 places it in family Orassitellidfe or Craesitellitida;, as the family is 

 now called. 



NEW AND INTERESTING EOCENE MOLLUSCA FROM THE GULF 

 STATES, by Gilbert D. Harris (Proc. Acad. Nat. Sci., 1896, pages 

 470-482, pis. XVIII-XXIII). This paper relates to new and in- 

 teresting forms in the " Lea Collection of Eocene Mollusca " in the 

 Academy of Natural Sciences of Philadelphia. Seventeen new spe- 

 cies are described and a number of specimens that are much finer 

 than the types, have also been figured.
