Female pores on Somite xiv, slit-like, large, dorsad of 

 the inner couple of setae. 



Nephridiopores in line with outer setae (or inner setae 

 in E. sylvicola, Beddard). 



Generative Apparatus. — Three pairs of sperm-sacs in 

 Somites x, xi, xii. Testes and ciliated rosettes in Somites x, 

 XI, enclosed in median sperm-sacs. The two sperm-ducts of 

 each side run separately to the prostate, which is much elon- 

 gated, and occupies Somite xvii and following somites. This 

 communicates with a "bursa copulatrix" in Somite xvii, 

 into which also open two small glands. The bursa contains a 

 curved chitinous penis. 



There appear to be two pairs of ovaries (Beddard) in 

 Somites xiii and xiv, enveloped in membranes which are con- 

 tinuous with the wall of the spermatheca. Into the neck of 

 the latter there also opens an albumen gland. The ''ovary" 

 in Somite xiv is also an ovisac. 



[The gizzard occupies Somite vi. 



In Somites x, xi, there are ventral diverticula of the ali- 

 mentary tube ; in Somite xii, lateral calciferous diverticula. 



The nephridium consists of a slightly coiled tubule, the 

 terminal portion of which is only slightly dilated to form a 

 duct.] 



Species 1. E. decipiens, E. P., 1872; Antilles. 



2. E. lacazii, E. P., 1872; Martinique. 



3. E. peregrinus, E. P., 1872; Rio Janeiro, 



Surinam. 



4. E. boyeri, F. E. B., 1886; New Caledonia. 



5. E. sylvicola, F. E. B., 1887; British Guiana. 



Note. — Horst believes that the first four of these are in 

 reality the same species, and proposes to retain the name of 

 E. decipiens for them.
