SPARGANOPHILUS SMITHI. 
A large specimen, natural size, ventral view. 
Anterior part of the body, side view, showing tubercula pubertatis ridges, and their anterior extension to 
the center of somite xi. The dorsal and ventral termini of clitellum marked by x. 
The anterior somites, ventral view. The spermiducal pore is seen about half way between set 1 and 2 aid 
the tubercula pubertatis in xix/xi. 
Two of the clitellar somites, side view, showing tubercula pubertatis ridge. v. ventral. d. dorsal side. 
SPARGANOPHILUS SONOM2. 
The same as 122, but from Sparganophilus sonome, showing the tubercula pubertatis ridge to consist of a suc- 
cession of separate tubercles, two or three on every somite, with the groove very nearly in the center of each 
papilla. 
SPARGANOPHILUS SMITHI. 
Longitudinal section of the anterior somites, composed from seyeral sections. v. sg/. ventral septal glands in 
vy, vi, vii. s.v.spermtanks. s. s. sperm-sacs. f. four large folds of the dorsal vessel in somites xiy—xvili. 
sp. gl. prostates. 
A series of outline drawings of spermathec# from one specimen. 
SPARGANOPHILUS SONOM 2. 
Outlines of spermathece from a single specimen. 
SPARGANOPHILUS SMITHI. 
Cross-section of septum xi/xii. 
Cross-section of the body; the Roman numeral indicates the somite.
