Description of the Califormian Specimen. Body cylindrical without median 
lines. Posterior and especially the anterior portions of the body somewhat 
narrower than the middle; head (Fig. 61) of a rounded conical form, not con- 
stricted from the body, mouth terminal. Posterior end (Fig. 60) of the same 
diameter as the immediately preceding portion of the body, obtusely rounded 
terminally; the small, round cloacal aperture is terminal. Cuticle (Fig. 62) 
areolated: the brownish areole vary somewhat in size, are irregularly polyg- 
onal, and do not form rows but are well separated from one another; a few 
small interareolar bristles are present. Color: a clear chocolate-brown, head 
paler, a deep reddish brown ring around the mouth. Length, 130 mm. ; greal- 
est diameter, 9 mm. 
Description of the Cuban Specimen. Body nearly cyclindrical, with dorsal 
and ventral median grooves. Head cyclindrical, narrower than the portion of 
the body immediately preceding, terminally truncated (Fig. 76) ; this plane of 
truncation is slightly convex, the mouth situated in its centre. The anterior 
portion of the body is gradually attenuated, of less diameter than the middle 
portion. Posterior end of the body (Fig. 75) obliquely truncated, in that the 
dorsal margin projects farther caudad than does the ventral margin; the pos- 
terior end of the body is flattened on its ventral surface. In the medio-ventral 
line is a shallow narrow groove, which passes dorsad on the terminal aspect of 
the body, this groove being deepest at the dorso-terminal margin of the body. 
Within this groove lies the terminal cloacal aperture, Cuticle (Fig. 77 
areolated : areolæ low, irregularly rounded in outline, smooth superficially, 
close together; the areolæ are very little darker than the inter-areolar spaces; 
between them lie thick, conical hairs, which are higher than the areole. 
Color a uniform grayish brown, head lighter; the mouth is surrounded by a 
narrow reddish brown ring, and the vertical groove at the posterior end of the 
body is also of this color. Length, 112 mm.; greatest diameter, 1 mm. 
Comparison, There is some doubt in my mind whether these specimens 
«should be attributed to G. violaceus Baird, but they certainly come closer to this 
species than to any other, and until further specimens are examined from these 
localities may best be placed under this species. But we know that platy- 
cephalus and densareolatus come very close to violaceus in the structure of the
