Beddard calls them, spermiducal glands. These glands are, in Sparganophilus, situ- 
ated much further from the male or spermiducal pores than in any other genus, 
apparently quite independent of the pores. They are also subject to considerable 
variation, in some species being three, in others four; in one species none. Of the 
same nature I consider the forward parietal pair of glands in somite iii of Spargano- 
philus Eiseni, and it seems not unlikely that originally this genus possessed many 
more pairs of spermiducal glands, perhaps one in eyery somite. This location of the 
spermiducal glands favors greatly Beddard’s view that these glands were originally 
independent of the spermduct, and according to this view these glands are in 
Sparganophilus the most primitive of any. There is also much difference as to the 
development of these glands in the various species. Thus in Sp. Benhami the gland 
consists of two distinct parts and is both glandular and muscular, while in Sp. Smithi 
the muscular part is degenerate or undeveloped, the whole gland being very dimin- 
utive: Another point showing the primitive arrangement of the spermiducal glands 
is the absence of any copulatory sete, the common sete in their yicinity being 
unmodified. 
There is no doubt that a large number of species of this genus will soon be 
found on the American continent, especially as specimens appear numerous and widely 
distributed. In Guatemala I found them everywhere in springs and lakes, and a 
hasty examination of live specimens satisfied me that there were among them about 
three species, characterized by the position of the hearts, whether in viii—xi, ix—xi, or 
x-xill. Unfortunately my Guatemala collection was destroyed and only few speci- 
mens in poor condition remain. 
In this connection I will also call attention to another species of Sparganophilus 
not described below, but found by me several vears ago in the small lake known as 
Laguna Puerea, situated near the ocean at San Francisco, California, or in the same 
lake as I now find Sparganophilus Smithi. This species which [ have sinee been 
unable to re-collect, although I have made repeated excursions to the place and dug at 
the identical spot, offered much of interest and was undoubtedly a different form 
from any now described below. It was much shorter and thicker, about 5 em. long 
by 4 mm. thick, or about half as long and twice as thick as our smallest species now 
known. The hearts were, according to a fieldnote, situated in vii, vili, ix, x. The 
longitudinal lateral vessels began in xiv, but most interesting of all, the species 
possessed five distinct and large eve spots on the first somite and prostomium, an 
occurrence not recorded in any other of the higher earthworms. 
The specimens were very rare—I could only find two or three in an hour; they 
occurred in the clay soil near the shore at shallow depth. 
In connection with this it is most interesting to note that at that time I found 
no trace of Sparganophilus Smithi, which now occurs in the same lake in countless 
numbers, a worm many times longerand much thinner. It is impossible that I could 
be mistaken in regard to my former observations. My explanation is this: Formerly 
the Laguna Puerea was much lower, the bottom soil near the surface was clayey, while 
now the lake is several feet higher, the bottom soil near the surface is sandy. A
