touch ujDon a few essential points of importance in further characterizing this species 

 from its other American allies. The species is nearest related to /S^;. Benhami and its 

 subspecies. The main points of difference and similarity may be found in the com- 

 parative table of the species of Sparganophilus. Sp. Benhnmi is a much more slender, 

 form than 6^). Ekeni, especially as regards tlie body posterior to clitellum. The ven- 

 tral side of the genital regions in the two species differ. Thus in Sj). Benhami the 

 ventral depressed area between the tubercnla pubertatis and the oviducal pores is 

 circular or oval, while in /S'p. Eismi it is contracted in the middle, the shape of a sand 

 time-glass. The presence of a small parietal gland in somite iii in Sp. Eineni 

 distinguishes this species from all others known so far. This gland is paired, extends 

 considerably into the coelomic cavity, is racemose and opens to the exterior in front 

 setfc 1 and 2, and projects its free apex back through septum into iv. Another 

 character is the small size of the septal glands in vi, the corresponding pair in 

 8p. Benhami being larger. 



Sparganophilus Smithi n. sp. 



Definition. Length 20 cm. by 3 1-3 mm. wide; number of somites 1^5. Dor- 

 sal j)ores, the most anterior one between i/ii, the most posterior one between xii/xiii. Cli- 

 tellum dorsally 1-2 xvi-xxviii, ventrally xix-xxv. Tubercnla pubertatis xix-xxvii, dorsal 

 to spermidacal pores. Setre 3 and A dorsal. Spermiducal pore between xviii/xix, ventral 

 of tubercula pubertatis. Sperm-sacs in xi and xii. Spermathecre 4 pairs in each of 

 somites vii, viii, ix, and 1 pair in somite vi, slender, dorsal and lateral. Prostates 3 pairs 

 in 'xxii, xxiii/xxiv. No muscular duct. Anterior nephridium xvi. Septal glands in 

 iv, V, vi and vii about equal in size. No subpharynqeal parietal gland. Blood Gapillaries 

 on nephridia numerous. Blood sinus in sacculated intestine not continuous. Hearts in 

 viii, ix, X, xi, small. Color violet flesh, somewhat iridescent. Habitat, San Francisco, 

 California. 



Sparganophilus sonomae n. subsp. 



Definition. Length 20 cm. by 3 1-2 mm. wide; number of somites about 200. 

 Dorsal pores. Clitellum dorsally xvii-xxviii, ventrally xvi-xxix. Tubercula jn^berfatis 

 xix-xxviii, dorsal to spermiducal pore. Setm 3 and 4 dorsal. Spjermiducal pores 

 between xviii/xix, ventral of tubercula pubertatis. Sperm-sacs in xi and xii. Sperma- 

 thecce, two pairs in each of vii, viii, ix; one pjair in vi, not slender. Prostates 3 pairs 

 in xxiii, xxiv, xxv, no muscular duct. Anterior nephridium in xvi. Septal glands in 

 iv, V, vi, vii, about equal in size. No subpharyngeal parietal gland. Blood cap)illaries 

 on nephridia numerous. Blood sinus in sacculated intestine not continuous. Hearts 

 in viii, ix, x, xi, small. Color violet flesh, less iridescent than Sp. Smithi. Habitat, 

 Sebastop>ol, Sonoma County, California. 



Sparganophilus Benhami n. sp.

 namber of somites abotit 250. No dorsal pores. Clitellum, dorsally xv-xxiv; ventrally 

 xvii-xxvi. Tubercula pubertatis xviii-xxii, ventral to spermiducal pores. Setx 3 and 4
