1896,] FROM THE SANDWICH ISLANDS, 211 
boundary segments x./xi., is a single median papilla, upon the 
middle of each of which is a row, concave forwards, of large pores, 
which appear to correspond to glands like the capsulogenous glands 
of Perichete. Such glands have already been met with in 
Acanthodrilids (in Acanthodrilus rose), another fact among many 
which show the intimate relationship between the two families. 
The chtellum occupies segments xili.—xvi. 
The nephridia are of the diffuse type. 
The first septwm separates segments iv./v. The next three are 
moderatly thickened, and after the last of these come four, which, 
though not quite so thick, are to some extent strengthened. All 
these septa, beginning with the first mentioned, are attached to 
each other and to the parietes by numerous tendon-like muscular 
fasciculi. These latter extend for a segment or two farther back 
than that which is bounded by the last thickened septum. The 
last heart lies in the xiith segment. The dorsal blood-vessel is 
single. Two stout gizzards immediately following each other lie 
in segments v. and vi. In segments xi. and xii. are a pair of 
caleiferous glands. The intestine seems to begin in segment xvi. 
and has a well-developed typhlosole, which, however, is not 
apparent for the first ten segments or so, though it may be possibly 
present earlier as a rudiment. 
The sperm-sacs are a single pair in xii. This, however, may be 
a question of immaturity. On the other hand, although I detected 
two pairs of funnels belonging to the sperm-ducts, I could only see 
the testes of segment xi., and the funnels of segment x. were 
distinctly smaller than the posterior pair. 
The spermiducal glands are very long and coiled. There appear 
to be no penial sete associated with them. 
The spermathece are as usual in viii. and ix. The diverticula 
near to the external aperture are inconspicuous, but apparently 
tri- or quadrifid. 
Hab. Thana, Bombay (1500 ft. and 2500 ft. altitude). 
Remarks.—Though I do not propose, for the present at least, to 
create anew genus for this species, it differs in several points 
from any known member of the genus Benhamia. It comes nearest 
perhaps to Benhamia imermis, with which it agrees in absence of 
penial set and in the position of calciferous glands
