ANOMURA. 217 



10 to 14 fathoms. Fifteen specimens in all; two of the specimens were females 

 bearing eggs ; carapace of largest measured 2 centims ; found inhabiting shells of 

 Cerithium citrinum, Ranella granifera, Cancellaria sp., Turbo sp., Cerithium, 2 spp., 

 Seraphs terebellum, Pleurotoma sp., Triton sp., Strombus elegans. 



Cancellus investigatoris, ALCOCK (1). 



Locality : Gulf of Manaar, shallow water. One specimen ; carapace measuring 

 1'5 centims. 



Nematopagurus muricatus, HENDERSON. (See ALCOCK, 1.) 



Localities : (1) Gulf of Manaar, shallow water ; (2) near Chilaw Paar, Station IV., 

 9 fathoms. One male from each ; carapace measuring 5 millims. 



Nematopagurus sp. 



Locality : Gulf of Manaar, shallow water. A damaged male specimen, without 

 chelipeds and legs ; carapace measuring 6 millims ; cornea but little dilated ; antennal 

 acicle curved and setose, and as long as the eye peduncles ; ophthalmic scales well 

 separated ; rostrum small, obtuse, and rounded, projecting but little ; the ophthalmic 

 peduncles reach the middle of the terminal joint of the antennular peduncles ; vas 

 deferens protruding on both sides, the right one being much the longer. 



The character of the vas deferens shows that this form belongs to the genus 

 Nematopagurus, but, in the absence of all the appendages. I cannot venture to 

 identify it further.
