720 OLIGOCHAETA 



(48) AUolobophora nasonovii, Kulagin. 

 Dendrobaena nasonovii, Kulagin (fide Rosa, 15). 



Definition. Length, 90 mm.; number of segments, 170. Setae in eight rows. Clitellum, 

 XXr-XXIX. Hah.—Suchum. 



This species is, as Rosa (15, p. 45) points out, close to A. platyura; but he 

 holds it to be probably distinct ; it is evidently but ill defined. 



(49) Allolobophora bogdanovii, Kulagin. 

 A. Bogdanovii, Kulagin (fide Rosa, 15). 



Definition. Length, 662 mm. j number of segments, 110. Setae distant. Clitellum, XXV-XXX. 

 Tulercula pubertatis, XXVIIT, XXIX, XXX. Hah. — Suchiim. 



(50) AUolobophora caucasica, Kulagin. 

 Dendrobaena caucasica, Kulagin (fide Rosa, 15). 



Definition. Length, 40 mm. ; number of segments, 90. Colour dark red, darker above than 

 below. Setae in eight rows, equidistant. Prostomium completely dividing buccal segment. 

 Clitellum, XXF, XXVI-XXIX, XXX, XXXL Dorsal pores commence IV/F. Eab.—Kacila, 

 in the Caucasus {p., %oo ft.). 

 This is another doubtful form, of whose internal structure nothing is known. 



(51) AUolobophora berleyi, Hoest. 



Enterion platyurum, Fitzingek, Isis, 1833, p. 55a (in part.). 



Lumbricus terrestris, var. platyums, Obkley, MT. Akad. Math., xvi, 1880, p. 583

 A. platyura, var. depressa, RosA, Mem. R. Ace. Torino, 1893, p. 44. 



Definition. Length, 11 1 mm.; number of segments, I'^i. Setae distant. Clitellum, XXV- 

 XXX. Tubercula pubertdtis, XXVI-XXVIIL Male pores inconspicuous. Spermathecae 

 in VII-X, opening posteriorly by seta IV. Hob, — Europe.
