glands are present in connection with septa |, |, ^, projecting 

 forwards into the anterior of the two segments with which the 

 septum is in relation ; except that the most anterior gland appears 

 in sections to project backwards into v with its ventral portion, 

 instead of forwards into iv. The stomach is a marked dilatation 

 of the alimentary tube in segments x and xi ; its epithelial lining 

 consists of large cells arranged in definite longitudinal rows, each 

 cell with a cavity in its interior. Oesophagus and stomach are 

 markedly ciliated ; the oesophagus widens in xiv to become the 

 intestine. The salivary glands begin behind in segment vi, and 

 run forwards ventral to the oesophagus through v ; in iv they 

 are much coiled, and finally enter the pharynx. 



The lymph corpuscles are numerous circular or oval bodies, 

 granular and, except for the very distinct nucleus^ hardly staining. 

 The largest are 22-27^ in length. 



The dorsal vessel begins apparently behind the clitellum, 

 about the level of septum |f . 



The nephridia are of the compact type, small in size, the 

 anteseptal portion nearly as large as the postseptal ; there is 

 a marked constriction at the septum ; the duct is short, about 

 equal to the postseptal portion in length, and is directed down- 

 wards and backwards. The first nephridium is in vii. 



The cerebral ganglion is in segment ii ; it is somewhat oval in 

 shape, and not indented posteriorly. There are no " copulatory 

 glands" in connection with the ventral nerve cord. 



The genital organs have the usual situation. There are large 

 numbers of developing spermatozoa in segment xi. The male 

 funnel is short and stumpy, not more than twice as long as broad, 

 without everted margin. The vas deferens is very slender and 

 much coiled, and enters the penial bulb on the dorsal side of the 

 latter ; the bulb is approximately spherical. 



Segment xii contains ova, septum if being bulged backwards 

 as far as the posterior boundary of segment xiii ; the condition 

 might be described as the commencement of the formation of an 

 ovisac. 



The spermathecae are situated in segment v, in front of the 

 septal gland ; the ampulla is small, somewhat irregularly ovoid, 

 elongated, transversely, and with thin walls : it probably opens 

 into the oesophagus, though I did not see the actual aperture. 

 The spermathecal duct is long, narrow, coiled, in the main trans- 

 versely placed behind the septum ; there are no gland cells round 

 the duct or round the external aperture. 



Enchytraeus harurami, sp. nov. 



Specimens were obtained by myself and my pupil, L. Haru 

 Ram, B.Sc, on 24th March, 1914, from the duckpond in the 

 Zoological Gardens, Lahore ; they are thoroughly aquatic, living 

 under the same conditions as, and in company with, numerous 

 Naididae.
