spines on each of the lateral margins of the telson and moreover 

 these spines tend to arrange themselves in groups of three to five 

 smaller spines separated by larger spines. There are also differ- 

 ences in the proportions of the spines at the apex of the telson. 

 In L. afiops the inner pair of spines is twice as long as the next 

 pair and the spinules between the inner spines are about half as 

 long as the latter. 



Zimmer (1915 (3) ) has recorded L. apiops with a query from 

 the Indian Ocean. It seems probable that the single specimen at 

 his disposal really belonged to the present species. Zimmer 

 does not give the number of spines arming the lateral margins of 

 the telson but the spines at the apex, judging from his figure, agree 

 in their proportions rather with L. xenofs than with L. apiops. 

 The only difference I can see is that the small spinules between the 

 large pair of spines at the apex are about half as long as the 

 spines in Zimmer 's specimen and only one quarter as long as the 

 spines in mine. 



The species is an abundant one in the neighbourhood of the 

 Andamans, to judge by the large number of the specimens in 

 this collection. 



Genus Afromysis Zimmer. 

 Afromysis macropsis, sp. nov. 

 Text-figs. i5«-g. 



Locality. — Off Puri, Orissa, 4-4J fathoms. One male, 9 mm. 

 (Type.) 



Description. — Body smooth, without spinules ; carapace pro- 

 duced into a short triangular rostral plate with an obtusely rounded 

 apex ; eye long and narrow, recalling the eye of the genus Meso^ 

 podopsis, more than twice as long as broad, cornea occupying less 

 than the distal half of each eye and not wider than the rest of the 

 eye, pigment black. 



Antennal scale shorter than the antennular peduncle, about 

 seven times as long as broad, setose all round, distal articulation 

 well marked, a prominent spine on the outer distal corner of the 

 basal joint. 



Posterior thoracic legs rather. short and slender, tarsal joint 

 divided by a single transverse articulation. 



Telson one and a half times as long as broad at the base, cleft 

 for one-third of its length, cleft wider proximally than distally and 

 unarmed except for two long plumose setae, the lateral margins 

 armed with three spines proximally at the widest part ; these are 

 followed by a short unarmed portion of the margin and distally 

 there are about twenty spines ; the proximal eight or nine of these 

 spines are normal sharply-pointed short spines; the remainder are 

 blunt spines increasing in size to the apical lobes, the two or three 

 on the inner side of the apical lobes somewhat smaller but of the 

 same type. 



Inner uropod one and a half times as long as the telson, its
