718 OLIGOCHAETA 



First dorsal pore, IV/V. Spermathecae in IX, X, opening between TX/X, X/XT. Hab. 



Jassy ; Palestine. 



In the above definition I have, as usual, given the greatest length and the greatest 

 number of segments of the individuals studied by the describer of the species. It is 

 a remarkable fact that the smallest specimen, measuring only 58 mm. in length, had 

 the largest number of segments, while the largest specimen had the fewest segments. 

 The ventral setae of the segments x, xi, xiii, xxvii, are upon strongly marked papillae ; 

 these papillae appeared to be quite constant in the species. Only two pairs of sperm- 

 sacs were found lying in xi, xii. According to ROSA two tubercula occupy xxxii-xxxiv, 

 and the spermathecae are in x, xi. The sperm-sacs are four pairs. 



(42) Allolobophora japonica, MICHAELSEN. 

 A. japonica, MICHAELSEN, Arch. f. Nat., 1892, p. 230. 



Definition. Length, 42 mm.; breadth, i\ mm.; number of segments, 126. Clitellum, 

 XXIV-XXXI. Setae strictly paired, separated by equal internals. First dorsal pore, 

 IV/V. Tubercula pubertatis, XXVII, XXIX. Spermathecae two pairs in IX, X, opening 

 between IX/X, X/XI, in line with lateral xetae. Hab. Japan. 



Of this species there appear to be two varieties, which are only to be distinguished 

 by colour and size. I have selected the smaller form for description as the type, for 

 the reason that it comes first in MICHAKLSEN'S account of A. japonica. This form 

 is colourless ; the larger worms are a darkish red in colour, and measure 1 30 mm. in 

 length by a diameter of 5 mm. ; the body is composed of 155 segments. In both forms 

 the setae of the hinder end of the body are rather larger than those in front. There 

 are besides the tubercula pubertatis several papillae ; two pairs of these lie upon 

 segments xxii, xxv. Those of the first segment are in line with the ventral setae, 

 the second pair more dorsal in position.

Definition. Length, 47 mm.; diameter, 5 mm.; number of segments, 135. Setae not sir icily 

 paired. Clitellum, XXXII-XXXFI. Tubercula pubertatis, XXXIII-XXXV. Dorsal 

 pores begin III/ IV. Hab. Madeira ; Portugal.
