The Araneides of the Chevert Expedition have heen described 

 by H. H. B. Bradley, in the Proceedings of the Linnean Society 

 of New South Wales (vol. ii. part 2). 



A list of the spiders captured in the Seychelles Islands by 

 Prof. E. P. Wright, with descriptions of species supposed to be 

 new to arachnologists, by John Blackwall, F.L.S., accompanied 

 by notes by the Eev. O. P. Cambridge, has been published in the 

 'Proceedings' of the Eoyal Irish Academy (August, 1877), with two 

 excellent plates by Mr. Tuffen West. Four species of Salticus, 

 one Lissomanes, one Thomisus, one Olios, one Sparassus (?), one 

 Cluhiona, one Theridion, one Argy nodes, three Epeirce, one Nephila, 

 and two TetragnathcB are described as new. 



A memoir by Kramer on the classification of the Acaridce 

 appears in ' Archiv. f. Naturg.' (43rd year, 3nd Heft). Also, by 

 the same author, two remarkable new genera of Acaridce, Labi- 

 dophorus talpa and Pygmephorus spinosus, are described and 

 illustrated in the 3rd Heft of the same work. 



A memoir on the curious transformations which occur in 

 various species of mites, especially in the genus Trombidium, 

 with two plates, is given by M. Megnin (Ann. Sc. Nat., ser. vi., 

 vol. iv.). 



A remarkable genus of Acai^idee {Heterotrichus, belonging to 

 the Gamasidce), covered with strong bristles, is described by 

 Donnadieu, in the ' Microscopical Journal' for June last, in which 

 also appear a number of excellent illustrations of different Acaridce 

 by Tuffen West. 



A large magnified figure of the tick found in considerable 

 numbers in the woodwork of the roof of Blyborough Church, 

 supposed to be parasitic on the bats, of which a good many were 

 disturbed in repairing the roof, is given by Mr. C. F. George, in 

 the ' Quarterly Journal' of Quekett Microsc. Club, 24th Nov. 1876, 

 pi. 21 & 22 (and in ' Science Gossip,' 1877, p. 104). It is given 

 as the Argas Fischerii of Walcken., but it seems to me identical 

 with A. Pipist7'ell(B, Aud. 



The Acarideous genera Dermaleichus (= Analges), Freyana and 

 Picobia, are fully described, and illustrated with two fine plates, 

 by G. Haller, in Siebold and KoUiker's ' Zeitschrift' for November 

 last. Thirteen species of the first named genus, parasites on 

 birds, are described with very full biological details of both sexes 

 aud their transformations. Freyana anatina is parasitic on
