Remarks. — The type of this species is at Bamberg; it has not been examined by any 

 one since Muller. From the very short description it cannot be definitely assigned to any 

 particular species. 



Locality. — India.

The centrodorsal is very thin, discoidal, with a broad, very slightly convex, dorsal pole 

 1.5 mm. in diameter which bears numerous very small scattered tubercles among which, about 

 the border, are larger irregular flattened tubercles, frequently surrounded by a circle of the 

 smaller ones, apparently indicating the location of obsolete cirrus sockets. The cirrus sockets 

 are arranged in a single slightly irregular marginal row. 



Cirri XIII, 27 — 29, 25 mm. to 27 mm. long, very slender, gradually and slowly tapering 

 to a point, only slightly and irregularly curved. The first segment is very short, the second 

 about twice as broad as long, the third from about as long as broad to half again as long 

 as broad, the fourth or fifth and following about four times as long as broad, becoming slightly 

 shorter (from two and one half to three times as long as broad) toward the end of the second 

 third of the cirrus, and longer again terminally. The longer cirrus segments are very slightly 

 constricted centrally ; those in the outer third of the cirri have the ventral and dorsal profile 

 more nearly straight. The terminal claw is very long and very slender, about as long as the 

 preceding segment, with the tip more or less curved downward. 



The proximal edge of the radials, adjacent to the centrodorsal, is bordered by a row 

 of small rounded bead-like tubercles, and there are smaller and less conspicuous tubercles 

 scattered over their surface in the angles of the calyx. The IBr x are very short, more than 

 four times as broad as long; the IBr., (axillaries) are low triangular, twice as broad as long.
