Var. A was dredged in 30 and in 37 fathoms in Suvadiva, on a rough stony bottom 
and on the hard smooth bottom of a passage. 
Var. B was dredged in Suvadiva, Kolumadulu, South Nilandu, Haddumati, Mulaku, and 
Felidu in 830—45 fathoms on every kind of bottom. 
Var. C was dredged in Suvadiva and Kolumadulu in 34 and 35 fathoms on bottoms 
of rubble and broken shells respectively. 
It seems not unlikely that the dredgings of the “Investigator” and of Mr Gardiner’s 
Expedition have revealed a new and highly varietal species of Thalamita in deep waters 
near India, of which 7. ewetastica, var. spinifera, var. macrodonta, T. investigatoris and T. 
imparimanus are but varieties. The habitat of this species is probably in moderately deep 
water only. Allied to it, but separated from it by the form of the chelipeds and their 
equality in the male, is the species next described of which the only known specimen has 
been taken on the littoral.

Closely allied to 7. tmparimana Alc. 1900 (Iv. p. 87), but separated from it by the 
following characters : 
G@) Basal joint of antenna has a short crest consisting of two large teeth fused at 
their bases. 
(ii) Chelipeds of male equal, smooth, with a few scattered warts and scanty hairs. 
Outside the wrist are two ridges, and three spines, at the inner angle one spine. Outside
