? India.— Five medium-sized specimens ; one of these has the median 

 brachial carina tion exceptionally well developed.

Depth. — Littoral, and down to 8 (? 40) fathoms. 



Remarks. — In a series of specimens from Ceylon which I examined at the 

 British Museum the cirri are XXVI-XXIX, 23-26 (usually 25), 21 mm. to 22 

 mm. long; the outer segments are about twice as broad as long as in T. carinata, 

 and the last four taper rather rapidly. As a whole the cirri are rather slender 

 and weak, but very numerous, arranged in two and a partial third very irregular 

 marginal rows, giving a characteristic appearance to the animals. The lower 

 pinnules are stiffened.
