84 THE NAUTILUS. 
The work will doubtless be of the greatest assistance to all students 
of this rich fauna, and we hope that its talented and industrious 
author may succeed in bringing it to a good completion. 
List oF Texas Mottusca collected by J. D. Mitchell. This 
catalogue embraces both marine and fresh-water forms, and adds 
many localities to the published records of Texas shells. 
Nores oN SomME MARINE INVERTEBRATA FROM THE COAST OF 
British CotumsBra, by J. F. Whiteaves. A new Pecten, P. 
(Pseudamusium) vancouverensis is described and figured, and an 
adult specimen of Turcicula cidaris is for the first time illustrated. 
A CONTRIBUTION TO A KNOWLEDGE OF INDIANA MOLLUSCA, 
by R. Ellsworth Call (from Proc. Ind. Acad. Sci., III). The pres- 
ent paper is a preliminary list of the Indiana mollusk fauna, show- 
ing what has already been done toward an exact knowledge of the 
conchology of that State. Only authentic locality references are 
given, and nothing is admitted to the list on the strength of its 
occurrence in neighboring States. Of land shells, 58 species are 
enumerated ; fresh-water univalves, 47 species; bivalves, 102 spe- 
cies. No less than 53 species were originally described from Indiana 
localities. A bibliography is given, both of special and general 
works bearing on Indiana shells. The “ Contribution” is a step in 
the right direction, and will be welcomed by both Indiana collectors 
and those interested in the distribution of United States shells 
generally. 
Nores ON THE MIOCENE AND PLIOCENE oF Gay HEAD, Mar- 
THA’s VINEYARD, Mass., Etc., by W. H. Dall (Amer. Jour. Sci.., 
Oct., 1894). The result of Dall’s visit to this locality, examined 
by Lyell 50 years ago, and by numerous other geologists later, are 
important, verifying its reference to Miocene, in which it corre- 
sponds to the Chesapeake, “in all probability to the upper part of 
the Chesapeake, certainly not lower than the St. Mary’s fauna, and 
probably between that and the Yorktown beds.” At about 80 feet 
above sea level a small patch of shell fragments was found, in a 
stratum of sand, which is considered Pliocene. Nucula shaleri and 
Macoma lyelli are described as new from the Miocene; and Chry- 
sodomus stonei Pilsbry, originally described from stray specimens 
washed ashore on the New Jersey coast, was found, thus fixing its 
position, hitherto unknown, in the Miocene.
