A. flaims is probably only a variety of A. tetraedrus, while 

 Rosa's supposition may or may not be correct respecting A. 

 tetrago7iuriis. 



On page 3 the writer calls attention to the " remarkable 

 extension backwards of the prostomium (in Allolobophora 

 chlorotica), which reaches as far as the end of the fourth seg- 

 ment," to which I drew attention in Nature' on the strength 

 of material received from Ireland. 



It may be well in conclusion to supply an amended list of 

 Irish Worms" so far as known at the end of 1895, following the 

 nomenclature adopted by Beddard, with such modifications as 

 my judgment leads me to think necessary. 



Allurus tetraedrus (Savigny).— Tipperary. Also var. y?a!z/«j (not noted 

 by Beddard) from the same locality ; also found in Mitchelstown Cave. 

 A. macrurus, Friend. — Dublin. 

 Allolobophora caligrnosa, (Savigny). 

 A, turgrida, Eisen. 



I cannot but think Mr. Beddard ill-advised in putting the 

 two very distinct species formerly known as trapczoides and 

 ticrglda under one heading (A. calignosaj . I have examined 

 many hundreds of specimens from all parts of the country, 

 and could tell at a glance the one from the other. The author 

 makes a point of Michaelsen's discovery of an "intermediate 

 form which showed on one side of the body the character of 

 one species, and on the other the character of the other 

 vSpecies." I have often observed the same thing, and wonder 

 it has not occurred to Mr. Beddard to ask what bearing such 

 facts have on the question of hybridity — a question which, 

 though treated by Rosa and myself, seems to have been en- 

 tirely overlooked in the present memoir. 



A. terrestris (Savigny).— Takes the place of the old A. longa, Ude. 

 It is, however, not given by Beddard as an Irish species. I have re- 

 ceived it from Cork, Tipperary, and elsewhere. 

 A. foetida (Savigny). — Cork and Valencia. 

 A. chlorotica (Savigny). — Cork and Tipperary. 



A. Eiseni (Lrevinsen).— Takes the place of Dendrobcma Eiseni. Found 

 in Dublin. The author has done well for the present, no doubt, to 

 sink several of the generic terms which had been adopted by various 

 authors, for this and other species. I think, however, that the genus 

 will bear division into three or four sub-genera. 

 A* subrubicunda, Eisen. — Tipperary.
