712 OLIGOCHAETA 



the fully ripe ones had spermatophores attached to the body. The other eight showed 

 traces of tubercula on segments xxix, xxx. Unfortunately Michaelsen made no 

 mention of the presence or absence of spermathecae, -which would have decided the 

 question ; until accurate information is forthcoming that the spermathecae are missing 

 frequently in the typical A. auhruhicunda, I think it necessary to retain Rosa's species 

 A. constricta.

Definition. Length, about do mm. ; diameter, 3 mm.; number of segments, 165. Clitellum, 

 XXX-XXXV. Setae as in A. complanata. Tubercula pubertatis, XXXI-XXXIF. 

 Spermathecae, two pairs in X, XI, opening in line with third setae, between IX/X, 

 X/XI. First dorsal pore, X/XI or XT/XII. Sab. — Italy ; Germany ; Spain ; Argentine. 

 This species has been described by Rosa and by Ude ; the descriptions of these 

 two writers differ in some small points ; in others the observations of Ude supplement 

 those of Rosa. In the definition of the species I have followed Rosa, only adding 

 to the facts given by him the position of the first dorsal pore, not mentioned by 

 Rosa, but referred to by Ude. Ude's specimens were rather larger, measuring up 

 to 150 segments. The clitellum is a little more extensive^ extending over segments 

 xxix, XXX-XXXV ' ; the tubercula pubertatis form a groove which reaches from the 

 middle of segment xxx to the middle of segment xxxv. The position of the first 

 dorsal pore varies from x/xi to xi/xii. On the authority of Ude I add (as he did 

 doubtfully) Luvibricus stagnalis of Hoffmeistbb as a synonym. I do not, however, 

 see any grounds for this identification ; ' Lumbrieus stagnalis ' does seem to belong 

 to this section of AUolobophora, but it might also be A. veneta — indeed the extent 

 of the clitellum is more suggestive of this species. Rosa mentions that this species 

 has the same odour of garlic that characterizes A. complanata and A. transpadana; 

 from the anterior segments it emits a colourless fluid, and, after the fifteenth, a yellow 

 fluid. This species is said by Rosa to have bilobed spermathecae. 



'■ Rosa (15, p. 60) thinks that Ude had both this species and A. studiosa (which Rosa unites') in his 

 hands at the time that he wrote the description.
