1914-] J- Stephenson: Oligochaeta jrom Northern India. 349 



The above description is not as full as could be desired ^ on 

 account of the small size of the animal and the impossibility^ of 

 examining it by dissection, A number of sections were also 

 damaged through the presence of matter in the alimentary canal 

 which interfered with the cutting. The description will, however, 

 enable the form to be recognized when it is again met with. Its 

 small size, the presence of the large glandular structure in connec- 

 tion with the pharynx, the complete series of septa from ^ onwards, 

 and the characters of the genital setae will serve to distinguish it. 



The species is especially peculiar in being meganephric. As 

 to there being one large (relative to the size of the animal) neph- 

 ridium on each side in each segment there can be no doubt ; in 

 my original notes I find a statement to that effect in the middle 

 of the description of the external characters ; which indicates, 1 

 think, that the nephridia must have been visible through the thin 

 and probably semitransparent body-wall. The statement is borne 

 out by the sections, which I have again carefully examined for 

 this purpose. That the nephridia are comparable to the megane- 

 phridia occurring, for example, in the Lumbricidae, is, however, 

 not certain. I have failed to find, in the sections, an}^ evidence of 

 their attachment to the septa, and especially of their piercing the 

 septa in the typical manner, with the funnel on one side and 

 the bulk of the organ on the other. On the contrary, the trend of 

 the tube, where it can be most distinctly made out, is backwards 

 from the external aperture rather than forwards towards the 

 anterior septum. Owing to a lamentable accident, whereby a 

 number of my most carefully preserved specimens were thrown 

 away b^' an ignorant laboratory boy, any further examination of 

 the original specimens is impossible, and I am left only with a 

 series of longitudinal sections of the anterior portion of one of my 

 examples. 



Eutyphocus incommodus (Bedd.). 



Pusa (Bengal) ; lo-ix 1912; Bishambar Das. Two specimens. 



Basi Muda (Hoshiarpur District. Punjab); Aug. 1913; Md. 

 Ibrahim. Numerous specimens. 



Ambala (Umballa) ; Aug. 1913 ; Ibrahim. Numerous speci- 

 mens. 



Length 90-112 mm. ; breadth 4 mm. ; colour brownish olive. 

 Segments 141-162. 



The prostomium shows a combination of the pro- and tany- 

 lobous characters ; there are present both the transverse groove 

 which in prolobous species marks off the prostomium from the first 

 segment, and also the two longitudinal grooves between which, 

 in tanylobous species, the prostomium is continued backwards to 

 furrow h (compare Beddard's description of E. nicholsoni, i, 

 p. 197, with which he states E. incommodus agrees). 



First dorsal pore \\ or fl. 



Septum i is slightly thickened, ' moderately ; f, to, tt are all 

 slightly, or in the case of the last two it may be moderately.
