(Plates VII. & VIII.) 



In July of last year (1891) I received from Professor Jeffrey Bell 

 three bottles containing Earthworms which had been presented to 

 the National Collection. With the permission of Dr. Giinther, I 

 was allowed to make an examination of these specimens, and to 

 treat them in any way necessary for their identification. 



I wish to express my thanks to Dr. Giinther for this privilege, and 

 to record my appreciation of Prof. Bell's kindness in allowing me to 

 examine many Earthworms which from time to time have come into 

 his hands for identification. 



The contents of the bottles were as follows : — 



A. Three small worms [Plutellus perrieri, n. sp.] collected at 



Masset, Queen Charlotte's Island, British Columbia. Pre- 

 sented by the Rev. T. H. Keen. 



B. A single specimen {^Microchceta papillata, n. sp.] from Port 



Natal. Collected and presented by H. A. Spencer, Esq. 



C. A single specimen [Microchceta belli, n. sp.] from East 



London, Cape Colony. Collected and presented by H. A. 

 Spencer, Esq.

 the mature forms, under the impression that it belonged to the same
