they are about three times as long, and have the greatest circumference 

 at the third instead of the half of their length. 



The dorsal pores commence at XIX. 



The nephridia are diffuse. 



The pharynx is large. 



There is a pair of floculent mucous glands with three lobes each in 

 segment III. 



The gizzard is single, of considerable size, and lies in VII, while in 

 VIII, there is a soft crop-like portion joined by a distinct line. 



In segment XV are well marked calciferous glands, which, viewed 

 from the head, radiate from the oesophagus in a fan-like manner. 

 Each is divided into two distinct lobes, the dorsal cut up again into 

 two smaller lobes, and the ventral lobe in three parts. 



The intestine begins in XVI. 



There are no cseca, and apparently no typhlosole. 



The dorsal vessel is single, and the hearts are in XI, XII 

 and XIII. 



There are two pairs of spermathecse in VIII and IX. 



They are very small, possibly a young specimen. 



They open very close together, and consist of an oval pouch with a 

 short duct bearing a small tubular diverticulum. 



The sperm-sacs are not well developed, but seem to occur in IX 

 and XII. 



The spermiducal glands in XVII and XIX are tubular. They are 

 twisted regularly and present a sort of sausage-like appearance. 



The exact position of this worm is uncertain. It can hardly belong 

 to Acanthodrilus, as its nephridia are entirely diffuse. Though having 

 some affinities with Mr. Beddard's genus Octochcetus, it probably does 

 not belong to it, as the dorsal vessel is not double, the male pores 

 are not borne on papillae, and the calciferous glands are very distinct 

 indeed.

For the present it had better remain in Benhamia, from the general 

 type of which it differs in several respects. 



The setae are not closely paired, but B, mexkana has the dorsal pair 

 further apart. 



The clitellum only extends to XVII ; in B, curia it goes no further 

 than a part of XVIII.
