Introductory. 



I HIS paper deals with the Brachyurous Crustacea collected hy Prof. A. C. Haddon 

 during his first expedition to Torres Straits in 1888. The collection comprises about 

 87 species, three of which are described as new. Owing probal:)ly to the fact that 

 attention was given to collecting the smaller and less conspicuous forms, a number of 

 interesting and little-known species were obtained, some of which I have redescribed and 

 figured. From the same cause, however, the determination of many of the specimens 

 proved to be a matter of no little difficulty, and the identification of one or two of the 

 more obscure species is at best pro^dsional. 



Of the three species here described as new, Cryptociiemus Iladdonl belongs to a genus 

 hitherto comprising only four species, all of which are known only from single 

 specimens. Pilummis cristipes is apparently very distinct from any known species, and 

 its title to inclusion in the extensive genus Pilumiius may perhaps be disputed. 

 Lamltrus confragosus belongs to a genus already overburdened with species, but, so far 

 as the means at my disposal enable mu to judge, it seems to deserve tlie distinction of a 

 specific name.
