cent. The chelipecls are long — one half longer than the body 

 and more than three times as long as the other legs, — slender, 

 and cylindrical ; the fingers, which are not two thirds the 

 length of the palm, are singular in being rather hair}". 



The second to fourth thoracic legs are slender and ex- 

 tremely short, being not quite as long as the carapace (with 

 the rostrum) ; they all have the meropodite strongly carinated 

 along the anterior border and the dactylopodite (which has 

 the nsual spiny posterior border) short. 



Colours in life milk}- red above, milk-white below. 



An egg-laden female from Station 115, 188-220 fathoms, 

 measures about 24 millim. from the tip of the rostrum.

XXXVI. — Corylophida3 a?i^ Trichopterygidfe /o?//2f? /n the 

 West-Indian Islands. By the Rev. A. MATTHEWS. 



I AM indebted to the Committee of Natural History of the 

 British Museum for the permission to examine and describe 

 the insects which form the subject of tliis memoir ; they were 

 collected in the West-Indian Islands, chiefly in Grenada and 

 St. Vincent, by Mr. H. H. Smith, to whom much credit is 

 due for the careful manner in which they have been mounted 

 and preserved, since almost every specimen has retained its 

 full com])lement of limbs — a matter of no small difficulty and 

 of somewliat rare occurrence. 



Although the collection contains more than 1000 indi- 

 viduals, the number of species is comparatively small ; very 

 few examples of the smaller and more interesting kinds seem 

 to have been found, Mhile those of larger size are represented 

 by immense series, in one case exceeding oOO sjiecimens. 



'^I'he jirevailing clinrncter of both Corylophidre and Tricho- 

 pterygida? inclines to tlic tropical American tyjie and does not 

 present any special peculiarities, except, perhaps, in Throsci- 

 dinm invisihilc ; for, although this insect has already been 

 found in many tropical regions — in Ceylon, where it was 

 discovered by Ilerr Nietner, in the Cape-Verd Islands by 

 Mr. "Wollaston, and in Central America by Mr. Champion — 

 yet in all those localities it appears to be rare ; tiie West- 

 Indian Islands, however, seem to be its head-quarters, more 

 than fifty specimens having been taken by Mr. Smith in 

 Grenada and St. Vincent.
