16 TRANSACTIONS OF THE [oct. 23, 
the entire morainal region of the island, just as they may be 
found in the other regions examined, although not always con- 
taining any paleontological evidence of their origin. 
A few pieces which T picked up on the road between Menem- 
sha and Squipnocket Ponds seemed to promise some results, but 
they were too fragmentary for determination. 
In a subsequent communication * Prof. Shaler describes the 
results obtained from a study of the molluses contained in this 
material. The conclusion seems to be irresistible as to its Cre- 
taceous age, and the discussion in regard to its origin and dis- 
tribution is more nearly in accord with my own, but he is still 
unable to accept all the interpretations here advanced. 
Prof. R. P. Whitfield has kindly subjected the specimens in 
my possession to careful examination, without however reaching 
very satisfactory results, owing to their poor preservation. I 
quote as follows from his communication to me on the subject : 
“The box of fossils sent I have examined, but can make but little of 
the contents. * * * The Camptonectes is the best thing among them. 
* * * The Ostrea might be identified with O. congesta, Conrad, but I am 
not by any means certain that it is that shell. * * * There are one or 
two other shells—an Hwogyra, a Solen, and Shaler’s new genus, [See 
his Fig. 1.] * * * But I would not say unequivocally that they are 
Cretaceous,’’ 
Following is the list : 
Camptonectes Burlingtonensis, Gabb.? (Not C. parvus, Whitf.) 
Exogyra ostracina, Lam.? (Shaler, Fig. 19.) 
Huogyra sp? (Looks like #. arietina, Roem.) 
Ostrea congesta, Conrad ? 
Ostrea sp ? 
Lyonsia? (Same as Shaler’s f. 11, but not Lucina.) 
Mytilus sp? 
Corbula sp? 
. Some fragments of a Solen (not Leptosolen biplicata, Conrad). 
10. Shaler’s new genus, probably. (Shaler’s f. 1-1lb, ‘* Compare 
Myoconcha.’’) 
11. A gasteropod, indeterminate.
