and much resembling, the beak of a parrot. This mandible was 
partially enveloped in a tough white muscle and was connected with 
the digestive organs by a muscular gullet. On each side of the head 
was a Jarge eye about two inches in a diameter. The crystalline 
lens, when dried, were clear and bright and closely resembled large 
solitaries (I have seen the lenses used for settings). The gladius, or 
internal shell was about eighteen inches long, composed of shining 
white cartilage, and shaped like a large quill-pen, with the pen point 
towards the tail. I found about fifteen of these mollusks, but have 
been unable to identify them and would be pleased if some one 
could give me the probable name. 
GENERAL NOTES. 
Nore on CarycHiuM EXILE (C. B. Apams).—This Jamaican 
species was originally described in Adams’ Contributions to Con- 
chology, III, p. 88 (Oct., 1849) as Pupa evilis; and Pfeiffer retains 
the species in Pupa in the Monographia Heliceorum III, p.556. It 
is omitted from the Monographia Auriculaceorum. Bland in Journal 
de Conchyliologie, 1872, p. 46, first refers the species to Carychium. 
In this genus the name is preoccupied by H. C. Lea for a species of 
the United States described in 1841. The Jamaica form will, there- 
fore, stand C, exile Lea, var. jamaicensis Pilsbry (see Nautilus VIII, 
p- 63, figs. 15, 16), although some would probably consider it dis- 
tinct from the United States species. P. exilis Ad., C. exile Bland, 
becoming a synonym of the variety described by myself.—H. A. P.

the Falls of the Ohio is one that is very rich in numbers, but rather 
poor in species,” the total number being but ten species.

This Bulletin, which contains 132 pages and 22 plates, is a very valu- 
able addition to our knowledge of the Cretaceous Mollusca. Pre- 
ceding the descriptions of species, is a thorough discussion of the 
geological features of the region. There are enumerated 77 species 
of invertebrates, 50 of which are described as new; all but 7 ot the 
species are mollusks.
