be the same species. Lumbricus terrestris of LINNAEUS being a compound of many 

 species, I follow SAVIGNY. 



(5) Allolobophora cyanea (SAVIGNY). 



Enterioii cyaneum, SAVIGNY, Me"m. Ac. Roy. Inst. Fr. (Analyse), v, 1826, p. 181. 

 Lumbricus cyaneus, DuGES, Ann. Sci. Nat., (2) viii, 1837, p. 21. 

 A. studiosa, MiCHAELSEN, Arch. Ver. Nat. Meckl., 1890, p. 50. 



Definition. Length, 120 mm.; breadth, 7 mm. ; number of segments, 156. Clitellum, XXIX- 

 XXXIV. Tubercula pubertatis on XXX-XXXIII. Setae not strictly paired ; the distance 

 between i and 2 is greater than that between 3 and 4 ; anteriorly, the setae are closer 

 together. First dorsal pore, XI/XII. Spermathecae in X, XI, opening between IX/X, 

 X/XI, provided with diverticula larger than pouch extending into segment in front. 

 Had. Europe ; Argentina. 



The colour is dirty grey, anteriorly pale violet ; the distances between the setae are 

 thus given by MICHAELSEN: 'iv-iv = i-i; i-i > i-ii > ii-iii > iii-iv ; ' anteriorly, 'i-ii< 

 ii-iii > iii-iv.' It is stated that the diverticula resemble those of A. complanata (see 

 BEDDABD, 13). 



(6) Allolobophora mammalis (SAVIGNY). 



Enterion mammale, SAVIGNY, Me"m. Ac. Roy. Inst. Fr. (Analyse), v, 1826, p. 181. 

 Lumbricus mammalis, DUGES, Ann. Sci. Nat., (2) viii, 1837, p. 22. 

 A. celtica, ROSA, Boll. Mus. Zool. Torino, 1886, No. 2. 

 L. (Allolobophora) mammalis, VATLLANT, Anneles, p. 148. 

 A. (Dendrobaena) celtica, FRIEND, J. Linn. Soc., 1892, p. 297. 



Definition. Length, 40 mm. ; breadth, 2 J mm. ; number of segments, 100. Clitellum, XXXF 

 XXXVI. First dorsal pore. Tubercula pubertatis on XXXIIf, XXXIF. Setae in eight 

 rows, the intervals increasing from below upward. Hob. Brittany ; England ; Scotland. 



This species shows that remarkable alternation in the position of the nephridio- 

 pores which is characteristic of other species of the genus, and which has already 

 been dealt with. 



(7) Allolobophora foetida (SAVIGNY). 



Enterion foetidum, SAVIGNY, Me"m. Ac. Roy. Inst. Fr. (Analyse), v, 1826, p. 182.
