angles) of which the middle two are narrow rounded and prominent 

 beyond the outer two which are broad : the latter are well separated 

 from the supra-orbital angles, which are arched and are about the same 

 breadth as the middle frontal lobes. 



Antero-lateral borders cut into 4 acute teeth {including the outer 

 orbital angles) of which the first and last are the largest. 



Posterior border of dorsum of carapace straight, but forming a 

 curve with the postero-lateral borders, its length is half the greatest 

 width of the carapace. 



Orbits large, their major diameter about two-fifths the width of 

 the inter-orbital space, the inner angle of their lower border is not 

 dentiform, and they have no particular dorsal inclination. 



Basal antenna- joint less than the major diameter of the orbit in 

 extreme extent, its crest is smooth. 



C helipads of usual form : three spines on the anterior border of 

 the arm, none on the posterior border, the distal half of the upper 

 surface with squamiform markings : inner angle of wrist strongly 

 spiniform, three spinules on the outer angle ; hand with 5 spines, in the 

 usual position, the two behind the finger-joint the smallest, there are 

 2 or 3 obscure costae and some indistinct squamiform markings on the 

 outer surface : fingers shorter than the palm, especially in the larger 

 cheliped. 



Legs slender : the merus of the last pair is more than twice as 

 long as broad and has the usual spine on the posterior border, the 

 same border of the propodite of this pair has 2 or 3 spinules. 



6th abdominal tergum of male much broader than long, with 

 gradually convergent sides. 



Three specimens were dredged by a Danish Expedition off Trin- 

 comalee in 2 fathoms, and have been very kindly lent to- me for exami- 

 nation by Dr. H. J. Hansen. The carapace of the largest specimen is 

 6 millim. long and 9 miilim. broad.

" The carapace is broadly transverse, and is covered witli a close, 

 whitish pubescence, the transverse ridges which cross its dorsal surface 

 are not more distinct than in Thalamita admete to which species and to 

 Thalamita savignyi, Thalamita intermedia is nearly allied. 



" Of the six lobes of the front the median are smallest, and vsepar- 

 ated by a narrow and rather deep incision, the submedian and lateral 

 are subequal, the latter slightly overlapping the former ; th^ lateral 

 lobes project somewhat less than the others.
