the next it was distal, the proximal and distal sections of the 

 shaft being respectively 37/x and 33/'; in the next, these propor- 

 tions were 38/* and 26m ; and in the outermost seta of the bundle 

 they were 41/* and 26/^: i.e., the nodulus is, relatively to the 

 length of the seta, progressively more distally situated in the 

 more laterally placed setae of the bundle. So again : — in the 

 innermost seta of a bundle the nodulus was slightly proximal to 

 the middle; in the next, proximal section: distal: : 37/^: 31/^, 

 and in the outermost, proximal : distal : : 38/'' : 28 /'. 



The innermost seta of each bundle is also a trifle slenderer 

 than the others, and there is a gradual thickening from inner to 

 outer, the outermost bemg the thickest. 



There are no coelomic corpuscles. 



The retractor muscles of the pharynx are a number of 

 strands, inserted into the pharyngeal wall as far forwards as the 

 anterior boundary of the third segment, and passing back ob- 

 liquely to the parietes, some being attached as far back as dissepi- 

 ment f. .Surrounding this part of the alimentary tube, in seg- 

 ments iii-vi, and especially on its dorsal side, is a mass of tightly 

 packed fairly large spherical or ovoid cells, apparently glandular. 

 Chloragogen cells begin in segment vi. There is no stomach. 



The dorsal vessel is situated dorsally on the intestine, not 

 ventrally or laterally as in a number of related forms. There are 

 four vascular loops, in segments vi-ix ; Michaelsen (3) and Bous- 

 field (2) give five as the number in this species. 



The first nephridium is in segment vii. 



Fam. ENCHYTRAEIDAE. 

 Fridericia bulbosa (Rosa). 



Found at Wagah, a few miles outside Lahore, by Mohammed 

 Afzal Husain, in January, 1912. 



Length about 8 mm. Segments 30-37. Prostomium short, 

 rounded. Clitellum including segments xii--xiii. 



The setae are curved at their inner ends, straight for the rest 

 of their extent, bluntly pointed ; their length is about 28m, and 

 breadth nearly 3/^. In front of the clitellum the ventral setae are 

 usually 4 per bundle, in which case the arrangement is that 

 characteristic of the genus, — the two middle setae of the bundle 

 are shorter and thinner than those on each side of them. In 

 segment ii there may be only one seta on each side ; in other 

 segments in front of the clitellum there may be three setae per 

 bundle. Behind the clitellum the ventral setae are usually two 

 per bundle ; in one specimen all ventral bundles throughout the 

 body comprised two setae only. The lateral setae are usually two 

 per bundle ; in front of the clitellum there may be three. Seg- 

 ment xii is entirely without setae. 



Dorsal pores are present from segment vii onwards 



The pharynx is in lii ; its roof is composed of much elongated 

 columnar epithelial cells, which form a sucker-like plug. Septal
