one segment back. The calciferous glands will thus, in a normal 

 specimen, occupy segments x-xiii, and the intestine would begin 

 in XV ; the last heart would be in xiii, the testes in xi, vesiculae 

 seminales in xi and xii, spermathecae in vii and viii. The gizzard 

 seems to have the normal position for the genus. 



Notoscolex striatus, sp. nov. 

 (PI. xxvi, figs. 3-5.) 



Rotung, alt. 1300 ft. ; under stones ; 2i-xii-i9ii. Four specimens, one 



much smaller than the rest. 

 Upper Rotung, alt. ca. 2000 ft. ; found in earth when road-making ; 4-i- 



1912. A single specimen, the hinder end incomplete. 

 Same locality, 5-i-i9i2. Several specimens, some headless or tailless. 



Three specimens were examined and dissected, one from each 

 capture. 



Length 8| inches ; diameter max. 5-6 mm.; colour pale yellow- 

 ish or pale grey throughout, except clitellum which is light brown. 

 Segments 297. 



Prostomium relatively minute, prolobous, under cover of 

 segment i. The first three segments consist of single annuli ; iv 

 and V are biannulate; vi-xii are triannulate, though there may 

 be slightly marked subsidiary annulation in addition ; and the 

 same may be said of the post-clitellial segments. 



The first dorsal pore is in furrow to ; all are conspicuous. 



The setae are all ventral ; they are small, considering the size 

 of the worm. Behind the clitellum ab are moderately closely 

 paired, cd less closely ; ab = f-^ aa (more posteriorly = J aa) = f-|- 

 be; be slightly >cd. In front of the clitellum the setae are 

 often difficult to see ; in vii the ratios were ab slightly > ^ aa, be 

 = cd= i^ab, but these latter ratios are variable ; dd=f-^ circum- 

 ference. 



The clitellum embraces segments xiii-xv = 3 ; dorsal pores 

 and setae are present. 



A very characteristic genital area is present over the ventral 

 portions of segments xvi, xvii and xviii (fig. 3). In shape it is 

 rectangular, extending longitudinally from the level of the setae 

 of xvi to those of xviii, and transversely embracing the region 

 between the lines of setae c of each side. In colour it is brown, 

 the pigmentation being best marked all round the borders of the 

 area and over a longitudinal midventral tract. The centre of the 

 area, - the midventral portion of segment xvii, — is depressed. 



Next to the pigmentation, the most conspicuous feature of 

 the area is the presence of a pair of longitudinal grooves. They 

 are narrow, with definite margins and a rather wavy course ; they 

 traverse segment xvii in the line of setae a, or between a and b, 

 and at or just beyond both the anteirior and posterior limits of the 

 segment they bend outwards, thus taking an oblique course, — 

 more transverse than longitudinal, — for a short distance before 

 terminating near the border of the pigmented area.
