752 SUMMARY OF CURRENT RESEARCHES RELATING TO 



an anatomical account of the various systems of the body. The eggs 

 are also described. They are very closely alike in the two groups — e.g. 

 in showing the same sort of peculiar " ovum-stigma," which is restricted 

 bo MEallophaga and Anoplura. Then follow lists of hosts and the asso- 

 ciated species. 



£. Myriopoda. 



Studies on Millipedes.* — Karl W. Verhoeff discusses in particular 

 the family Craspedosornidas and its German representatives. He contrasts 

 the genera Craspedosoma and Macheiriophoron, establishes a new genus, 

 Tatrasoma, based on Atraetosoma carpathicum Latzel, defines the sub- 

 genera of Craspedosoma and Pyrgocyphosoma, and describes a number of 

 larval forms. 



Habits of Scutigera coleoptrata. f — J. Kiinckel d'Herculais has 

 some interesting notes on this long-legged centipede, which frequents 

 houses. It hides in crevices during the day ; it pursues flies (especially 

 Fannia scalaris) at night. It throws itself on the fly, enswathing it with 

 its long limbs ; it injects poison from its forceps ; it chews the dead 

 body, ingesting only the soft parts ; it may kill three or four at once 

 without stopping to eat. As a fly-catcher it does good service. 



7. Onychophora. 



New Species of Peripatus from Grenada. J — Charles T. Brues 

 describes Peripatus barbouri sp. n., which he and G. M. Allen found 

 close to the Grand Etang Lake in the Island of Grenada. It belongs to 

 the section of P. edwardsi. The body is entirely without dorsal colour 

 markings. There are 30-31, usually 31, pairs of legs in the female. 

 Its closest affinities are with P. trinidadensis from Trinidad, which lies 

 about ninety miles to the south-west of Grenada. It has also close 

 affinities with P. imthurmi, P. sedgwicki and certain forms of P. dominicae. 

 The author also discusses P. juliformis Guild, var. swainsonse Cockerell ; 

 P.jamaicensis Grabham and Cockerell, and an unidentifiable specimen 

 from British Honduras. 



5. Arachnida. 



Cavernicolous Gamasids.§ — A. Bonnet describes four new species 

 of Gamasus and one of Pergamasus collected from caves and the like 

 by M. Yire. 



Studies on Injurious Mites. || — Giacomo del Guercio has made a 

 zoological and practical study of the Eriophyida? which attack buds, 

 e.g. Eriophyes corylii/allarum and E. pyri. 



Monograph on Tarsonemidas.lf — Guido Paoli deals with the family 

 Disparipedidte, which have " a more or less subdiscoidal body, and the 

 cephalothorax protected by a more or less expanded clypeus which some- 

 times covers the rostrum and the first and second pairs of limbs."
