several species new to science. It is my intention to make several col- 

 lecting trips through the State during June and July, 1915, but the task 

 of making a complete collection for the State is not to be completed in a 

 few weeks by one man. 



Earthworms are easy to collect and no great difficulty is experienced 

 in caring for the collections. The most interesting forms are to be ex- 

 pected in uncultivated areas such as woodlands, stream banks, and the 

 margins of swamps and lakes. Many interesting forms may be taken 

 under logs and under the bark of old logs. The worms are especially easy 

 to collect in the spring when driven from their burrows by the heavy 

 rains. At such times they may be picked up in large numbers from roads 

 and sidewalks. I wish to gain a more extended knowledge of the distri- 

 bution of Diplocardia in the State and to know what forms are found in 

 the unglaciated areas of the State. If any members of the Academy will 

 aid in securing materials, I shall be very glad to have the material and to 

 return named specimens in exchange. I shall be glad to correspond with 

 any one who may be interested in such work. 



Following is a list of species I have taken in Indiana together with 

 some notes as to the habitats in which the worms were found. The space 

 of this paper is not sufficient for descriptions of the species. The monograph 

 by Michaelsen is the most authentic single work on the group. 1 The 

 nomenclature used in this list is that of Michaelsen's monograph, except 

 where the nomenclature has been modified in his later papers.- 



Family Megascolecioe. 



Genus Diplocardia (Garman). 



1. Diplocardia communis var. typica Garman. 



This form is quite common about Urbana and in other parts 

 of Illinois. I have not found it in Indiana. 

 D. communis var. singularis Ude. 



Collected under logs in recently cleared land near Culver, 

 Marshall County. I have other specimens collected in 

 Putnam and Vigo counties, which are very similar to 

 singularis but very much larger and differing in minor 

 points.
