136 O/i some Earthoorini from India and Palestine. 



An ovarian chamber is present ; tlie ovaries arc ])ion)iiieiit 

 frinj^ed projections on the anterior wall. The ovisacs arc 

 small projections into segment xii. 



The spcrmatliccal ampulla is small and snbspherioal ; the 

 duct is not much coiled. The atrium, in segment vii., is a 

 large tongue-shaped strncture, with a constriction a quarter 

 or one-third of its length from the body-wall ; the margins 

 of the atrium are slightly lobed; the duct joins its lower 

 portions. 



Madapur, 3500 ft., Coorg. 



Helodrilus (Dendrobaa) samarigcr (Rosa). 

 Huldah, Judsean Mountains; 5. iv. 1921 {T. Aharoni). A 

 single specimen, mature. Called the "dew-worm." (231- 

 B.M.) 



Helodrilus {Allolobophora) aharonii, sp. n. 



Rchoboth, Palestine. Three specimens, in poor con- 

 dition {T. Aharoni). (219 B.M.) 



The longest specimen is 105 mm. long and 4 mm. in 

 diameter. Segments 141. Colour light brown, no difference 

 between dorsal and ventral surfaces. Prostomium minute, 

 tanylobous, with, however, a transverse groove atross the 

 tongue one-third of the way back. Dorsal pores exist from 

 groove G/7 backwards. 



The setse are very closely paired ; aa==\\bc; dd is rather 

 less than half the circumference. 



The clitcllum is not very distinct, but appears to take np 

 nine segments, xxx.-xxxviii., with a '^ walW which embraces 

 segments xxxiii.-xxxvii. The male pores are indistinctly 

 indicated as whitish thickenings on segment xv., between 

 the lines of b and c. The ventral setpe of segments x., xi., 

 and xii. are on whitish cushions. 



Septum 5/6 is somewhat thickened, 6/7, 7/8, and 8/9 are 

 much thickened, 9/10 and 10/11 somewhat so, and 11/12 

 slightly. 



Calciferous glands are present in segments x., xi., and xii. 

 The gizzard probably occupies segments xvii. and xviii., but 

 the septa are so thinned as to be almost unrecognizable. 

 The last hearts are in segment ix. 



The male funnels are in segments x. and xi,, and appear 

 to be free (a delicate testis-sac would, however, in the 

 condition of the specimens not have been distinctly recog- 

 nizable). Seminal vesicles are present in segments ix., x., 

 xi., and xii. ; those in ix., xi., and xii. are large and only 

 slightly lobed ; those of segment x. are very much smaller. 

 Sperniathecfc, small and spherical, are present in line with 

 the lateral setcc, opening in 9/10 and 10/11.
