THE NAUTILUS. 19 



journal (V. 28, p. 205) is published a note from the late Thomas 

 Bland, recording a similar occurrence in a specimen of S. ohliqua 

 Say. 



S. ovalis decampii Tryon. Described originally from Marshall in 

 this state. 



S. ovalis peoriensis Wolf. A number of years ago, at the sug- 

 gestion of Dr. James Lewis, I sent examples of a Succinea, common 

 in this vicinity, to Mr. John Wolf, of Canton, Illinois, who identi- 

 fied them as a form he had named as above. I am not aware that 

 a formal description has ever been published. It is a well marked 

 form, easily separated from ovalis, and occurs abundantly in all 

 parts of the state. It is closely allied to S. decampii Tryon and 

 may be identical, but differs in color and lacks the black margin 

 said to be characteristic of that species. 



S. ovalis higginsii Bid. Specimens from Alpena received from 

 Dr. W. A. Nason and said to have been identified by Dr. James 

 Lewis, are the only ones I have seen from this state. The speci- 

 mens referred to lack the parietal tooth supposed to be characteristic 

 of the form.

LITTORAL LAND SHELLS OF NEW JERSEY. 



BY WM. B. MARSHALL. 



H. A. Pilsbry's list of shells, published under the above title, in 

 the April Nautilus, is deficient by at least one species. In 

 August, 1890, I collected one specimen of Succinea avara Say at 

 Cape May, N. J. The exact locality was on the ocean front, at 8th 

 Avenue, Mt. Vernon, between Cape May City and Cape May 

 Point, and was not more than 200 feet from the line of high tide. 



Mr. Pilsbry says, " The Atlantic shore of New Jersey is so sandy 

 that few land snails find suitable conditions there." It is very true 

 that land snails are very uncommon along the shore, but, in my 

 opinion, their rarity is due to some cause other than the nature of 

 the soil. The chalky dead shells of mollusks and crustaceans, which 

 are abundant in the vicinity of the shore, furnish the snails a ready 

 supply of lime; and the wild ])ea vines which grow in tangled 

 masses, covering large areas of ground, afford a succulent article of 

 diet.
