652 General Notes. 
CRUSTACEA.—Dr. A. Walter describes (Bull. Soc. Imp. Nat., 
Moskau, 1887) two new phyllopods (Apus heckelii and Artemia 
asiatica) from the Russian Transcaspian province. 
The species of the genus Podon are reviewed by Poppe in the 
Abhandl. Nat. Verein zu Bremen, Bd. X. new species (P 
schmakert) is described from Shanghai, China. 
C. F. Lutken has a paper on the whale-lice (Cyamus) in Vidensk. 
Selsk. Skr. Kjobenhaven, IV. He points out the identity of certain 
species described by Dall with those of previous authors, and 
re-describes, with a full-page plate, Dall’s Cyamus scammoni. __ 
Carl Bovallius, (notes on the family Asellide, communicated 
to the Royal Swedish Academy of Science, December 9th, 1885,) 
makes the family to consist of thirteen genera, three of which, 
Iamna, Iathrippa and Iais, are new. The two forms of Iamna 
were formerly referred to Iaera; Iathrippa is formed to receive 
Janira longicauda, while Iais includes the new species I. hargert 
and the Jaera pubescens of Dana. 
ARAcHNIDA.—Herr Doenitz describes (Stzb. Gesellsch. Naturf. 
Freunde, Berlin, 1887) the habits of two new trap-door spiders of 
Japan, belonging to the genera Atypus and Pachylomerus. P. fra- 
garia, unlike the rest of the genus, excavates its tubes in the soft 
bark of the camphor-trees or of the cypress (Cryptomeria) and 
closes it with a door, which it carefully covers with moss like that 
covering fhe rest of the tree. Doenitz also describes (l.e.) the 
copulatory habits of a Japanese species of Linyphia. 
A. Poppe communicates to the Abhandlungen (Band X.) of the 
Scientific Union of Bremen a valuable review of the parasitic mites 
belonging to the families Sarcoptide and Chelytide. The paper 
contains, among other things, a catalogue of all the known species 
of bird-mites (Analgesinz), arranged according to hosts. 
Jose . Hancock describes (Proc. Am. Phil. Soc’y, XXV. 
107) a new species of Datames (D. MEROE POEP Laredo, Tex. 
Dr. H. C. McCook, in a recent visit to London, found the origi- 
nal drawings by John Abbott which formed the basis of Baron 
Walckenaer’s descriptions of the American species of spiders. He 
gives the results of his studies of these drawings and the conflicts 
of priority of nomenclature between Hentz and Walckenaer 1m the 
Proceedings of the Philadelphia Academy (1887, p. 74). 
Brrps.—Mr. F. A. Lucas oe V.) gives a historical sketch of 
Bird Rocks, in the Gulf of St. Lawrence, and describes a recent 
visit to the place.
