the more complete segmentation of the posterior part of the 

 deutomerite in Metamera schubergi Duke, 1910, known from 

 the intestine of certain leeches, and the segmentation of both 

 protomerite and deutomerite in Tseniocystis legeri Cognetti, 

 1911, from the coelom of an oligochaete, but there are various 

 important differences. 



Habitat. — Intestine of Eunice siciliensis Grube : Andaman 

 Islands, Port Blair.

narrowing behind the middle, and posteriorly drawn out into 

 a narrow rounded tip. It is generally twisted upon itself, 

 presenting a number of turns of a spiral and a number of 

 marginal projections where the spiral is turning round to run 

 over the other surface. Nucleus oval or spherical, with 

 a single karyosome, generally situated in the anterior half of 

 the body. Some individuals are also found in an untwisted 

 or only partially twisted condition. 



Dimensions. — Length of the body in a twisted individual 

 318-5 ju., maximum width ^l'?>ii, diameter of the nucleus 37-5 ju,. 

 A partially twisted individual measured 398-4 /x, mth a maxi- 

 mum width of 170-2 /i,. 



Remarks. — In addition to the typical twisted individual 

 there are in the preparations a number of partially twisted or 

 untwisted individuals which are beheved to be of the same 

 species. One such individual shows an indication of a narrow 

 protomerite and a retracted bluntly conical epimerite. Typical
