(36} AUolobopliora georgii, Michaelsen. 

 A. Georgii, Michaelsen, JB. Hamb. wiss. Anst., vii, 1890, p. 3. 



Deflnition. Length, 29 mm.; breadth, a| mm.; number of segments, no. Clitellum, 

 XXFIII, XXIX-XXXV. First dorsal pore IV/V. Tubercula piihertatis on XXXI, 

 XXXIII. Setae strictly paired. Spermathecae in X, XI, opening between IX/X, X/XI, 

 in line with seta 4, Hab. — Valencia, Spaiti. 



This species comes nearest to A. trapezoides. 



(37) Allolobophora limicola, Michaelsen. 

 A. limieola, Michaelsen, loc. cit., vii, 1890, p. 10. 



Definition. Length, 90 mm.; breadth, 4 mm.; number of segments, 127. Clitellum, 

 XXJX-XXXr. First dorsal pore IV/V. Tubercula pubertatis on XXXIII and XXXIV. 

 Setae paired, the lateral closer together than the ventral. Spermathecae, two pairs in IX, 

 X, opening on to IX/X, X/XI, in line with dorsal setae. Hab. — Hamburg; in 

 a morass. 



The worm when alive is transparent, and flesh-coloured in front; behind it is 

 ■ almost colourless. The ventral setae of segments xxx-xxxii, xxxv, stand in some 

 specimens upon papillae ; in addition to these, there are often conspicuous papillae 

 upon segments ix, xii, occupying the space between the dorsal and ventral setae. 



(38) AUolobophora antipae, Michaelsen. 

 A. Antipae, Michaelsen, loc. cit., viii, 189 1, p. 16. 



Definition. Clitellum, XXV-XXXIII. Setae strictly paired, very delicate. First dorsal 

 pore IV/V. Tubercula pubertatis on XXX, XXXI. Hab. — Jassy. 



This species has been described from a fragment, which wanted the hinder end 

 of the body ; hence no measurements can be given. The worm has no integumental 

 pigment. On the tenth segment there are a pair of papillae on a line with the 

 lateral setae.
