Mr. Pocock has also described, in the Ann. awl Mag. Nat. Hist., a 

 new species of BJiax, found by Lieut. Graeme Batten at Kohat. His 

 notes on scorpions of the genus Duthus has also an interest to Indian 

 students of this archaic group of animals. 



Mons. E. Simon has described the Arachnida found by Drs. 

 Radde and Walter and A. Conchin, during the years 1886-87, in Central 

 Asia and Turkestan, in the Verhandl. d. K. K. Zool. Bot. Gesellsch. 

 in Wien ; and, in Spengel s Zoologische Jahrbiicher, Dr. A. "Walter has 

 described the species of Galeodes found in the same expedition, compris- 

 ing seven species of three genera — Galeodes, Rhax, and a new genus, 

 Karschia. 



In the Proceedings of the Zoological Society, the Rev. 0. P. Cambridge 

 describes some new Araneidce, among them Idiops colletti, from Meik- 

 tila in Burma, collected by General Collett, C. B., whose interesting 

 account of the nests of these spiders is given in the paper. The planting, 

 as it were, of the lids of these nests with lichen and pieces of grass 

 resembling those growing round the nests, is specially noticeable. 



Griostacea. — The Crustacea of the Afghan Delimitabion Commission 

 have been described by Mr. Pocock. They comprise only two forms, 

 Hemilepistus klugii and Gammarus pulex, which appear to have been also 

 found by Dr. Walter among the Trans- Caspian land and fresh- water 

 Crustacea he has described in SpengeVs Zool. Jahrhilch. He remarks 

 that of Isopods his collection contains only land forms, of which six 

 species are mentioned, and notes that the otherwise so widely distributed 

 fresh-water genus Asellus is not found east of the Caspian — also that 

 Telphiisa finds its extreme northern limit in Turcomania. Dr. J. G. 

 de Man describes a number of new or rare species of Brachyura from all 

 parts of the Indo-Pacific ocean region, but not many are from Indian 

 Seas. 



Chmtopoda. — Dr. A. G. Bourne has described in our Journal some 

 Earthworms from Dehraand Mussooree, including a new species, Typhceus

In the Annals of the Genoa Museum, Dr. D. Rosa describes certain 

 Indian Perichcetidce found by Sig. L. Fea in Burma ; including two new 

 species, P. fece, from Tenasserim, and P. birmanica, from the Irrawaddy. 



Botifera. — In a paper in our Journal, communicated by the Micros- 

 copic Society, Mr. H. H. Anderson has given some intei'esting notes on 

 some of the Rotifers inhabiting tanks about Calcutta, includino- several 

 new species, the most remarkable of which is B. mento, which lives in a 

 tube, whether its own or of some other ci-eature the author was unable 

 to discover.
