1) I regret having overlooked Cerfontaine's paper, but vrith re- 

 gard to Vejdovsky, I did not quote him because he worked with a 

 widely differing species. Similarly I did not quote Dr. Benha m him- 

 self, and indeed he also omits any reference to Vej do vsky in his first 

 study on Earthworms — presumably for the same reason (Q. J, M, S., 

 26, p. 272). 



2) Dr. Benharii states: — »For although it is perfectly easy, by 

 means of any ordinary elementary method (such as hardening in alco- 

 hol and staining in Borax Carmine) to demonstrate the structure of the 

 clitellum and the truth of Cerfontaine's statements, yet Mr. Cole 

 has seen no nuclei in the long club-shaped cells! (to which by the way, 

 he gives the cumbrous name of ,calceo-cutaneous' glands).« 



On p. 8 of the (unaltered) reprint of my paper in the Zool. Anz., 

 I figure the nuclei I am supposed not to have seen and on p. 7 I state 

 that they are 5 jx wide. (It is possible that Dr. Benham may have 

 mixed up my terms, and is referring to the calceo-cuticular glands. 

 If so, I admit not having seen such nuclei as he figures in the Quart. 

 Journ. M. S., 26, pi. 16.) 



3) I do not know what Dr. Benham means when he says that I 

 was unable to recognize the unicellular gland cells in the ordinary 

 hypodermis.
