1880. ] Recent Mollusca during the year 1879. 433 
“Notice of recent additions to the marine invertebrata of the 
North-eastern coast of America,” etc. Besides descriptions of 
many Polyzoa and a new Ascidian the author notes as new to the 
eastern coast, Xylophaga dorsalis Turton, Lunatia nana Moller 
(also found by Möller in Greenland, and by Dall in Alaska) and 
Idalia pulchella Alder and Hancock. Dendronotus robustus Ver- 
rill, is stated to be identical with and prior to D. velifer Sars, 
from Norway. 
In the Proceedings of the Academy of Natural Sciences of 
Philadelphia for 1379, p. 16, Mr. W. G. Binney mentions Arionta 
vowellt and A. facta Newc., with Binneya notabilis Cp., as found 
on the Mexican island of Guadalupe off the coast of Lower 
California. He suggests that the Mexican genus Xanthonyx is 
probably synonymous with Binneya. In the same periodical Mr. 
Andrew Garrett gives a list of land shells inhabiting Rurutu, one 
of the Austral (Pacific) Islands with remarks on their synonymy, 
geographical range and descriptions of new species; 1. c. pp. 17- 
30. It contains twenty-three species, of which eight are new. On 
page 31 of the Proceedings Mr. Garrett describes Gontobranchus 
albopunctatus, sp. n., from Huahine, Society islands. 
In the Canadian Naturalist, viii, n. s. No. 8, Mr. J. F. Whiteaves 
publishes a short paper of nine pages, “ On some marine inverte- 
brata from the west coast of North America,” which contains 
among other things a very interesting list of mollusks from the 
coast of British Columbia, one of which, Cardium richardsonii is 
described as new. This paper (though stated to be published 
Dec. 20, 1878), is of such interest to the students of geographical 
distribution that I include a notice of it here. It partially fills a 
gap which has long existed in our knowledge of the invertebrata 
of the fauna existing between Puget sound and Alaska. This 
fauna for the most part is Oregonian in character and contains 
few locally characteristic mollusks. 
In the report of the Chesapeake Zodlogical Laboratory (Johns 
Hopkins University), which contains the papers of Prof. W. K. 
Brooks, before mentioned, is a list by Mr. P. R. Uhler, of animals 
found at Fort Wool, in the Lower Chesapeake. This contains 
thirty-one species of mollusks, all of which had been previously 
known, though several were new to the region. It must be stated 
that the identification of one of these, as Chiton cinereus Lin., is 
doubtless an oversight; as that is a northern species, Arctic and
