On new Species of Palearetic Simuliide. 141 
appearance, suggest calciferous glands. But, if we compare 
Alma enini, Mich., we may assume for the present that they 
are receptacles for spermatozoa. I find no other sperma- 
thecee, nor are sperm-lunnels present in the specimen section- 
ized, The sexual apparatus being degenerate, I can only 
discover a few traces of the ovary or testes, especially in the 
twelfth segment. 
As I know all the Oligochets which have been found in 
this country, both indigenous and imported, I have no hesita- 
tion in saying that Anagasfer is a true British representative 
of the subfamily Criodriline. 
Definition: Anagaster fontinalis, sp. n. 
Length 2 inches, segments 100. Girdle on segments 21, 
22-32, 33, saddle-shaped, and very conspicuous. ‘Tubercular 
band on segments 29-31; these segments, as well as 11-14, 
being more tumid. Male pores, with large papilla extending 
over the two adjoining segments, on 15. No head-pore or 
dorsal pores, calciferous, cesophageal, septal, or coelomic 
glands. ‘Typhlosole with valve-like arrangement. Seminal 
vessels in segments 9-12, Large heart to vascular system in 
the tenth segment. Setee paired, not ornamented. Sperma- 
thecse appear to be absent; no muscular gizzard; pharynx 
modified laterally. 
Hab. Taken trom a well at North Terrace, Mildenhall,
