with the intestine in V ; duct short and narrow. Sperm-ducts narrow, 

 a few times longer than the funnel, which is long and narrow, with the 

 basal part sigmoid. A minute penial papilla situated ventrally and 

 close to the spermiducal pore. The sperm-ducts open independently 

 of these glands. One pair of long cylindrical sperm-sacs extend from 

 the testes forward through somites X to VII. No ovisacs. Nephridial 

 anteseptal consists of only the nephrostome. Lymphocytes of medium 

 size, thicker at one end, strongly granular. Color transparent white. 



Locality. — Lowe Inlet, British Columbia, June 3, 1S99, Prof. 

 Trevor Kincaid. " Under rocks at high tide." 



Characteristics. — This species undoubtedly stands near E. kin- 

 caidi., but differs not only in the form of the spermathecae, but also in 

 the emarginated brain, and in the presence of only one small penial 

 papilla near the pore of the sperm-duct. 



DETAILED DESCRIPTION. 



Brain. — The longitudinal diameter is about twice as long as the 

 transverse one. There is a central circular and somewhat globular 

 mass of fibers in the fibrous band. 



Spermathecce. — The diverticle is wide, in one spermatheca entire, 

 in the other indistinctly lobed, forming chambers containing balls of 

 spermatozoa. The duct resembles that of JE. kincaidi ; the diverticle 

 wider than in that species. The connection with the intestine at the 

 center and at one side of the organ. 



Sperm-funnels. — One of the funnels somewhat shorter than the 

 other. The longest funnel is represented by the figure (41, a). 



Spermiducal pores. — As in other species of this genus described 

 in this paper, no trace of any penial bulb. The sperm-ducts open in- 

 dependently of any glands. A small penial papilla close to the pore, 

 situated more ventrally. It contains two minor gland agglomerations 

 situated side by side, and two or three smaller ones situated nearer the 

 ganglion. As a substitute for a penial bulb there are numerous muscle 

 fibers connecting the ventral and dorsal parietes around the spermi- 

 ducal pore, just as in the higher Oligochteta, as for instance in Ponto- 

 drilus. 



Sperm-sacs. — They consist of two very large bodies surrounded by 

 a peritoneal membrane of great tougliness. They fill entirely somites 

 VIII to X, and encroach upon VII. The intestine is quite narrow in 

 the somites occupied by the sperm-sacs. The sperm-sacs are slightly 

 contracted by the septa. Compared with the sperm-sacs of E. kin- 

 caidi.^ those of the present species are two or three times as long, but 

 not quite so wide. They are readily dissected out without breaking.
