the other to the base of the inter-digital cleft). The fingers have pointed tip?;, they 

 meet throughout their length; apposed borders are toothed throughout, the distal 

 teeth being the larger; when clenched, the inner surfaces of the fingers taken together 

 are concave; an irregular pubescent groove runs along the proximal portion of the 

 upper surface of the dactylus. 



Walking legs flattened laterally, the dorsal border of meropodite, carpopodite, and 

 propodite in each is expanded as a considerable crest ; the ventral border of the 

 meropodite of each has distally two ridges, the anterior of which extends the whole 

 length of the segment, and is more prominent proximally, particularly in walking 

 leg 4 ; in walking leg 4, also, the ventral border of the propodite is expanded, so that 

 the segment is foliaceous ; there are traces of transverse grooves on the posterior 

 surfaces of the meropodites of all the walking legs; the posterior surface of the 

 propodite is dimpled. 



The dactylopodites of the first three pairs are fairly similar, somewhat compressed 

 antero-posteriorly, both anterior and posterior surfaces with a longitudinal groove, 

 dorsal border flattened and bearing a mat of short hairs. The dactylopodite of 

 walking leg 4 is foliaceous, but its flattened surface is only 0'36 as broad as that of 

 the propodite of the same appendage. There is a tuft of hair on the dorsal border of 

 the proximal portion of the meropodite of each walking leg.

Locality : Gulf of Manaar, one specimen. 

 Description: An adult male. C.l. = 15 - 0. 



Lophozozymus dodone (Herbst, 1801) A.3, p. 108. 



Localities : Off Mutwal Island, two specimens (adult 6, adult ?); coral reefs. 

 < rulf of Manaar, two specimens (adult 6 ) ; pearl banks, Gulf of Manaar, two specimens 

 (6*, '. young) ; Trincomalee. two specimens (young 6", young ? ). 



Description j Variability among the specimens concerns: (1) Index C.b. -r C.l. ; 

 and (2) the fact that most are somewhat concave laterally, but an adult male has 

 approximately straight sides.

Locality : ( lalle, one specimen. 



Description : -Adult female. < !.l. = 10*5. It is covered with a pubescence. The 

 most anterior of the three antero-lateral teeth is obsolescent. Traces of the network 

 of red lines are seen in the posterior and posterolateral regions with a lens,
