DESCRIPTIONS OF GENERA AND SPECIES 717 



(39) Allolobophora lissaensis, MICHAELSEN. 

 A. lissaensis, MICHAELSEN, loc. cit., p. 18. 



Definition. Length, 55 mm - > breadth, 3^ mm. ; number of segments, 123. Clitellum, 

 XXIX XXXVI. . First dorsal pore XIV / XV. Setae in eight rows. Tubercula pubertatis 

 on all of ditellar segment. Spermathecae, six pahs in segments V-VIII, X, XI. 

 Hal. Lissa. 



The setae are in eight rows, but are not separated by equal distances ; the 

 following is their arrangement : i-ii > ii-iii > iii-iv. The irregular position of the 

 spermathecae is due to the fact, that some of the pouches open anteriorly and others 

 posteriorly ; the first four open posteriorly on a line with seta 3 ; the fifth pair lies 

 either in the ninth or in the tenth segment, in the first case against the hind wall 

 of the segment; in one specimen these had an intermediate position projecting into 

 two segments (cf. A. complanata, BEDDAKD, 13). The sixth pair opens by the 

 front wall of the eleventh segment. 



(40) Allolobophora leoni, MICHAELSEN. 

 A. Leoni, MICHAELSEN, loc. cit., p. 15. 



Definition. Length, 90 mm.; breadth, 5 mm.; number of segment, 156. Clitellum, 

 XXni-XXXVI. First dorsal pore, IV/V. Tubercula pubertatis, XXX, XXXII. Setae 

 paired, the ventral median interval is less posteriorly and greater anteriorly than the 

 lateral. Spermathecae, eight to ten in each of segments X, XI. Hab. Jassy. 



This species is not very fully described by MICHAELSEN. Further details were 

 added by ROSA (15). It is unpigmented, like A. trapezoides. The post-clitellian 

 region of the body is angular ; the segments of the anterior part of the body are 

 tri-annulate. It appears to be uncertain whether the clitellum does not extend as 

 far as to the thirty-ninth segment ; ROSA, however, only found it to occupy xxvi-xxxiv. 

 The ventral setae of segments xii, xiii, xxii lie on slightly raised papillae. 



(41) Allolobophora jassyensis, MICHAELSEN. 

 A. jassyensis, MICHAELSEN, loc. cit., 1891, p. 17. 



Definition. Length, 95 mm. ; breadth, 4 mm. ; number of segments, 133. Clitel/nn/, 

 XXV III, XXIX-XXM . Tnbercula i.nbertati*, XXXI-XXXJ'. Setae xtr'ftly paired.
