A species of which the nearest ally is G. Hookeri, King, which has 

 however much narrower lea-ves not tesselate on the lower surface. This 

 is also allied to the Bornean species G. Beccariana, Stapf, which has 

 however much smaller leaves, not tesselate beneath.

The Pdg'^mt?^ collected by the "Investigator" during the season 

 1893-94, form a small but interesting collection of seventeen species, 

 for the opportunity of examining which I am indebted to my friend 

 Surgeon-Captain A. R. Anderson, I. M. S., the Surgeon -Naturalist of 

 the " Investigator." The small number of species is doubtless to be 

 explained by the fact tljat no special attention could be paid to shallow- 

 water forms ; had time and opportunity permitted, the number of these 

 might have been very largely increased. Of the seventeen species taken, 

 tw^o have been left unnamed, as the specimens by which they are 

 represented are either very joung or are in an imperfect state of 

 preservation. The collection also contains an undescribed Glaucothoe 

 which appears to be a larval form, and I have therefore not given it 

 a specific name. Of the fourteen named species no less than seven are 

 described as new, and the remaining seven — six of which are from 

 shallow water-— belong to previously known species. The large pro- 

 portion of new species is not remarkable when the deep-water habitat 

 of the majority is taken into consideration. The fourteen species are 

 included in no fewer than ten genera. 



The specimens were taken at six dredging stations, at five of which 

 the depth exceeded 100 fathoms, so that the collection may fairly be 

 described as a deep-water one. The greatest depth at which Pagurids 

 were taken during the trip was 719 fathoms, off the North Maldive 

 Atoll, where two new species of the characteristic deep-water genus 

 Parwpagurus were obtained. The last dredging station on the list is 

 a shallow-water one off the east coast of Ceylon, where from 28 fath- 

 oms six species were obtained, three of which are new. There are
