British Enchytnvids. By Rev. H. Friend. 593 



pair of oesophageal glands in 7, intestine enlarging behind them in 

 segment 8, where the dorsal vessel arises. Nephridia in front seg- 

 ments with small ante- and large postseptal continuing into the 

 duct. Could not find any long duct to sperm-funnel. Chloragogen 

 cells large, sparsely distributed among the septal glands. In most 

 cases the spermathecffi were undeveloped, but in one instance I 

 found a pair in the usual position, and a single one in the segment 

 behind, making 3 spermathecae in all. The nephridia in front of 

 the girdle seem to be normally 3 pairs in segments 8/9, 9/10, 10/11.

These worms occurred with numbers of Enchytrmus nigrinus 

 Bretscher, and might at first be regarded as identical with it, but 

 the shape of the setae, the coelomic corpuscles, the oesophageal 

 glands, blood-vessel, salivary glands, and other things soon arrest 

 attention.

18. Henlea rhsetica Bretscher. 



The author's description (Eevue Suisse de Zoologie, 1903, 

 xi. p. 115) may be summarized thus : — 



Length about 7 mm. Segments 45-50. Setae in anterior por- 

 tion of body 6-8, posteriorly 5-6 per bundle. Brain about twice 

 as long as Ijroad, slightly incised behind. Large coelomic corpus- 

 cles ; no salivaries seen. Widening of intestine in segment 8, but 

 no cesophageals. Dorsal vessel arises in the 9th segment, and 

 here as well as in 8 and 7 there are heart-like enlargements. Duct 

 of nephridium arises from the anterior portion of the postseptal. 

 Sperm funnel 2-3 times longer than broad. The long duct opens 

 into a prostate or atrial gland. There is no allusion to the sper- 

 mathecae.
