DESCRIPTIONS OF GENERA AND SPECIES 711 



This species is characterized by the above definition ; the account given by KosA 

 deals with but few points, besides those mentioned in the definition ; it is not quite 

 clear from his description whether the spermathecae are in segments xii and xiii or 

 in xiii and xiv ; he merely says that the external opening is on the line between 

 segments xii and xiii and xiii and xiv ; the shape of these organs appears to be 

 characteristic; they are described as being 'claviformi, molto allungati.' There are 

 special accessory papillae . upon segments xvi and xxvi, which bear the ventral setae ; 

 the last pair are not so constant as the fii-st, and are connected by a raised 

 transverse ridge. 



(33) AUolobophora smaragdina, Eosa. 



A. smaragdina, KosA, Boll. Mus. Zool. Torino, 1873, No. 130. 



Definition. Length, 80 mm.; breadth, 6 mm.; number of segments, 104. Clitellum., 



XXir, XXF-XXXUI. First dorsal pore, IV/F. Tuhercula pubertatis on XXX-XXXII. 



Setae paired, ventral in position. Spermathecae, two pairs in IX/X, opening IX/X, X/XI, in 



line with dorsal setae. Hah. — Bleiberg, Carinthia ; at looom. 



The most noticeable character of this species, when alive, was the bright green 



colour, which, as Rosa observes, is a rare colour among earthworms. The colour 



seems to be like that of A. molleri, Microchaeta rappii, and a Benhainia referred to 



above (p. 559). The sperm-sacs are four pairs in ix-xii, without any median 



sperm-reservoir. 



(24) AUolobophora constricta, Rosa. 



A. constricta, RosA, Lumbr. Piemont., 1884, p. 38. 



A. subrutaicunda forma constricta, Michaelsen, JB. Hamb. wiss. Anst., vii, 



1890, p. 15. 



Definition. Length (in alcohol), 20 mm., when alive up to 45 mm. ; number of segments, 



100. Clitellum, XXVI-XXXI. Setae paired hut not strictly. No tuhercula pubertati''. 



No spermathecae. Hah. — Italy. 



The reasons which led Michaelsen to regard this species as at most a variety 



of A. suhrubicunda were the variability in the tuhercula pubertatis coupled, of course, 



with the other points of agreement, such as small size and position of the clitellum. 



Out of twenty-two specimens of A. suhrubicunda collected, fourteen belonged to the 



variety ' constricta ' ; the rest were intermediate in characters. The first lot had no 



trace of tuhercula, and were partly mature and partly immature to some extent ;
