twice as long as its basal width. In the new specimen the 

 mandible has the proximal tooth more produced and acute 

 than in Annandale's figure and the interval between it and 

 the second equal to that between the second and third teeth ; 

 there is no accessory tooth on the inner margin of the distal 

 tooth. The rami of the first cirrus have 10 and 15 seg- 

 ments and the caudal appendages, which are little less than 

 half as long as the sixth cirri, have about 22 segments. No 

 males are attached to either specimen. 



In Annandale's key to the Indian species of the subgenus 

 Scalpellum (Rec. Ind. )lus. ix. 1913, p. 228) the entry 

 relating to this species should apparently read " margins of 

 tergum moderately excavated/' instead of " not excavated."

Description. — Female. Capitulum compressed, oval, notched 

 above, with 14 calcareous valves embedded in — and, except at 

 the umbones, entirely concealed by — a thick cartilaginous 

 layer. On the outer surface, which is covered with a very 

 short velvety pubescence, the areas of the valves are defined 

 by grooves and the lines of growth are strongly marked 

 (fig. 5, A). On paring away the cartilaginous layer the 

 calcareous valves are seen to be widely separated, but with 

 the margins not markedly excavated and with the lines of 

 growth shallow and rather widely spaced (fig. 5, B) . The 

 following description applies to the calcareous valves, not to 

 the superficial areas, except where the latter are mentioned. 

 Tergum irregularly triangular, apex projecting above that 

 of carina, recurved : cariual margin angled above the middle, 

 upper portion concave, lower straight or slightly convex ; 

 scutal margin slightly sinuous; oecludent margin slightly 

 convex, forming an even curve with margin of scutum. 

 Scutum triangular, basal width more than half its height, 

 apex overlapping tergum, oecludent margin slightly convex, 

 other two sides nearly straight, inner angle rounded. Carina 

 evenly curved, its a| ex projecting freely for a short distance 

 and touching or entering between the terga, its base rounded 

 and widely separated from carina! latera ; roof strongly 

 convex, defined bv a slight ridge on each side from the
