116 Address. [Feb. 



M. A., and the author deals with the whole question of the different 

 kinds of worms and their diseases. 



The Report of the Committee which was formed, in 1888, to inves- 

 tigate the mango-weevil, has been published in the Journal of the Agri- 

 Horticultural Sociehj of India. The Committee found no less than four 

 insects, all belonging to widely different orders, which pass their larval 

 existence, or part of it, in the mango. 



In the Bulletin de la Societe Zoologique de France, Dr. R. Blanchard 

 discusses the cause and frequency of double cocoons in different races of 

 the Bomhijx mori. 



Myriopoda. — The Myriopoda of the Mergui Archipelago, collected 

 by Dr. J. Anderson for the Trustees of the Indian Museum, have been 

 reported on by Mr. R. I. Pocock, in the Journal of the Linnean Society. 

 The Chilopoda comprise one new specimen. The Biplopoda are of greater 

 interest and all are figured : one new species of Glomeris ; two of 

 Panidesmiis ; two of Spirostreptus, and one of Spiroholus are noted. 



Mr. Pocock has also described the Chilopoda of the Afghan Delimita- 

 tion Commission, including two species, of which one — Scolopendra 

 truncaticeps, is new. 



Araclmida. — Mr. E. W. Gates has conti'ibuted to our Journal a 

 valuable paper on the species of Thelyphonus, or whip-scorpions, inhabit- 

 ino- Continental India, Burma, and the Malay Peninsula ; and Mons. E. 

 Simon the first part of a study of the Himalayan Arachnida, collected 

 by Messrs. Oldham and Wood-Mason, in the collections of the Indian 

 Museum. 



The Journal of the Bombay Natural History Society contains a paper, 

 by Mr. E. W. Gates, on the Indian and Burmese Scorpions of the genus 

 Isometrus, with descriptions of three new species — I. slwplandi, found only 

 at Palone in Burma; I. pMpsoni, from Tenasserim, and I. assamensis, 

 from Dhubri. 



The Arachnida of the Afghan Delimitation Commission have been 

 reported on by Mr. R. I. Pocock, who finds that they are more nearly 

 I'elated to Mediterranean forms than to the fauna of any other area. 

 Six spiders are described, of which three, viz., Tarantula medica, found 

 between Tirphul and Meshed ; Nemesia tubifex, from Gulran ; and 

 Bhax aurea, found between Hari Riid and Meshed, are new. The 

 scorpions include Buthus parthorum, sp. n., found between Hari Rud 

 Valley and Meshed, which appears to be allied to Tunisian forms ; 

 Buthus afghanus, sp. n., from the same neighbourhood, which is closely 

 allied to B. europoeus, the well-kaown S. European and N. African form ; 

 and Orthodactylus schneideri (L. Koch), which also has allies in the 

 Mediterranean area.
