1896.] J.R.Henderson — Some "Investigator'''' Paguridss. 535 



A female apparently adult, and a very young individual in sheila 

 (Ifurex ?), overgrown by an Epizoanthus. 



The larger specimen has lost its abdomen, but the carapace mea- 

 sures 10 mm. in length. 



Both, the median and lateral frontal projections are prominent 

 and subacute, the median being somewhat better marked than the 

 lateral. The eye-stalks are rather short, while the narrow and acute 

 ophthalmic scales are separated by a somewhat narrow interval. 

 The external prolongation of the second joint of the antennal pedun- 

 cle, and the antennal acicle, are both well developed ; the antennal 

 flagellum is not twice the length of the carapace, and is fringed with 

 long hairs. 



The chelipedes and ambulatory legs have a dense covering of long 

 yellowish hairs on their upper surface. The right chelipede is stouter 

 but only slightly longer than the left ; its fingers move in a horizontal 

 plaue, and have horny tips. The carpal and propodal joints show a 

 few acute denticles scattered among the hairs on the upper surface. 

 The dactyli of the ambulatory legs are provided with yellow horny 

 apices. 



I hesitate to describe this species under a new name as the single 

 adult specimen is very incomplete, and it is impossible to ascertain 

 whether sexual appeudages were present or not. If the speeies is an 

 Eupagarus, as is seems to be, it is probably new, and is chiefly charac- 

 terised by the form of its chelipedes, and the strongly marked 

 pubescence. 



17. Glaucothob. 



Station 150, off the North Maldive Atoll, depth 719 fathoms. 

 A single example measuring about 20 mm. in length. 



The right chelipede is granulated and considerably larger than the 

 left. Tlie abdomen is slighly folded on itself perhaps accidentally, 

 bat is not spirally twisted. The species agrees with 0. peronii, Milne- 

 Edwards (Ann. Sci. Nat , t. XIX. p. 334, pi. VIII. 1830), in its un- 

 equal chelipedes, whereas in G. rostrata, Miers, and G. carinata, Hen- 

 derson, they are equal. It is distinguished from Milne-Edwards' species 

 by the granulation of the larger chelipede, the presence of a rather 

 broad median frontal projection, and by the greater length of the 

 ambulatory (or possibly swimming) dactyli, which in Milne-Edwards' 

 figure are represented as about equal in length to the propodi, while in 

 our example they are fully one and a half times as long. Milne- 

 Edwards' example was also considerably smaller. 



Giaucothoe has been regarded both as an adult, and as an imnia-
