This species is a common littoral form. Friend also recorded it from 

 several fresh- water localities. There are copulatory glands in the 14th and 

 i5th segments.

Lumbricillus Evansi,* n. sp. 

 Plate X., fig. 10, A-F. 



These worms are 10-14 mm. long. The anterior ventral bundles contain 

 6-9 setee. In each segment the epidermis is covered with numerous rows of 

 small clear glands which alternate with fine lines. 



The brain (PI. x , fig. 10, a) is straight or slightly concave in front, 

 deeply cut behind, where it is somewhat broader than in front. It is slightly 

 longer than broad. There are two pairs of copulatory glands in the 13th and 

 14th segments, those in the 14th being the larger. 



This character is, however, very variable, as fig. 10, b, shows. No, 1 is 

 drawn from a Scotch specimen, No. 2 from an Irish one. The coelomic 

 corpuscles (fig. 10, c) are irregularly oval in shape, granular, and nucleated. 

 In some cases the ends are drawn out into fine points. The intestine is 

 covered with dark-brown glands. The girdle occupies segments 12 and 13. 

 It is composed of small granular glands. The dorsal vessel rises in the 14th 

 segment. There are three pairs of septal glands. The nephridia (fig. 10, d) 

 are formed of a small anteseptal, and a large broad, flat postseptal portion. 

 The duct rises just behind the middle of the postseptal, and is about as long 



* This species is named after Mr. W. Evans, of Edinburgh, who collected many species for me.
