usually disposed as a fan on the posterior extremity of 

 the body, while in one individual minute white grains 

 superficial to the brown pigment appeared all over the 

 body. In no case was there any tendency to the formation 

 of a dorsal white line. 



The eyes were reddish brown and crescentic in shape, 

 the ragged concave side being directed outward. The 

 anterior pair were much larger than the posterior, and 

 the latter were much closer together than the former 

 when the animal was well extended ; the two pairs, how- 

 ever, were not approximated as represented in the figures 

 of M'Intosh but on the contrary were separated by an 

 interval quite as great as in the case of Tetrastemma can- 

 didum for instance. 



The central stylet apparatus agreed precisely with the 

 figure given by M'Intosh (PL XIII., fig. 1), except in two 

 specimens wherein the handle of the central stylet was 

 long and with a straight posterior border as in the others, 

 but the corners were rounded off instead of sharp. 



A number of females containing numerous large ova 

 were seen but in no case was there any sign of commencing 

 development.

Nemertes neesii (Oersted). 



A young individual 3 cm. long dredged in about 20 

 fathoms off Peel on June 23rd, 1895, is the only example 

 of this species which has so far as I know been taken 

 below low water mark in the district. Large specimens 

 were commonly found on the shore in all suitable localities.
