DESCRIPTIONS OF GENERA AND SPECIES 569 



(17) Benhamia pallida, Michaelsen. 



B. pallida, Michaelsen, loc. cit., p. 258. 



Defluitiou. Length, 25 mm. Spermidueal gland slender ; penial setae present and of two 



hinds ; the larger are furnished at extremity with a few denticles which are occasionally 



hifid; the other setae are smooth. Ilab. — Togo, Bismarckslurg, West Africa. 



This species can hardly be distinguished from B. bolavi ; the only difference 



appears to be in the presence upon the free end of the penial setae of one particularly 



large denticulation, illustrated by Michaelssn in a woodcut (fig. b, p. 259). 



(18) Benhamia gracilis, Michaelsen. 



B. gracilis, Michaelsen, loc. cit., p. 258. 



Definition. Length, 60 mm.; breadth, ^ mm. ; number of segments, 145. Clitellum saddle- 

 shaped, Jilll—XX. Oviducal pore single and median just behitul intersegmental furrow, 

 XIII/XIV. Dorsal pores commence V/FI (?). Six median papillae on furrows 

 IX/X-XIII/XIF and XXIII/XXIY. Penial setae of two kinds ; one, the larger, with 

 a few broad bifid dentiaulations at the extremity ; the other, the smaller, with very few 

 simple denticulations. Hab. — Togo. 



(19) Benhamia malayana, Hokst. 

 B. malayana, HoKST, Zool. Ergebn. Ost-Indien, ii, p. ^^. 



Definition. Length, 20-30 mm. ; numher of segments, 95. Shin without any pigmentation. 



Clitellum, XIII-XX, complete. Prostomium continued on to buccal segment. First 



dorsal pore between segments Y/YI or FI/FII. Spermathecae with a single diverticulum. 



Penial setae of two kinds; the longer terminate in four spinehts, the shorter has a 



spoon-like extremity. Hah. — Flores ; Sumatra; Celebes. 

 H0E8T correctly remarks that this species shows considerable resemblances to 

 B. bolavi; it differs, however, in its stouter build, its complete clitellum, and in 

 having two instead of only one oviducal pore. The latter character also distinguishes 

 the present species from B. gracilis. B. pallida is another species which comes 

 very near to the present; the smooth setae of that form, however, are not stated to 

 have a spoon-like swollen extremity.
