the dorsal and ventral ganglia, and the relative thickness of the 

 epithelium and cutis, all show that this specimen belongs to the 

 species delineate/, and not to carta. The nephridia, however, possess 

 several openings on each side, and this fact, in view of Burger's 

 statement (3. p. 601) that there is only a single pair in E. delineata, 

 led me to examine a specimen of delineata which I procured whilst 

 at Naples. Here there were five openings on one side and seven 

 on the other, which seems to show that Burger's statement is 

 probably inexact. In all the other members of this family whose 

 excretory system has been worked out by Hubrecht (8. p. 115), 

 Oudemans (4. p. 144), or by myself (5 & 6), there have always 

 been more than one pair of ducts present, with the exception of 

 E. hemprichi, in which (5) they were altogether absent. 



EUPOLIA MELANOGEAMMA. 



Eupoliei melanorjrammet Punnett (6), 1900, = E. quinquelineata, 

 Burger (2). 



A very large specimen of this species was obtained, measuring 

 190 cm. in length and about 2*4 cm. in breadth at the thickest, 

 with a dorso-ventral depth of 7 mm. Five dorsal lines were present, 

 all being well marked and unbroken. This worm is one of the 

 largest Neinerteans recorded, being only exceeded in bulk by a 

 specimen of Lineus hngissi/mus recorded by Mcintosh ' and a 

 specimen of Cen'b ratal us lacteus measured by Yerrill (7. p. 435). 

 The internal anatomy of the species has already been described by 

 Punnett (6) and Burger (2). 



Earn. LiNEiDyE. 

 Lineus alboviitaits Burger. 



A single specimen of this easily recognized species was procured. 

 In the preserved state it measures about 9 cm. in length and 5 mm. 

 in breadth at the middle of the body. It appears to be a fairly 

 plentiful species with a wide distribution, having been recorded by 

 Stimpson a from Loo-choo, by Burger (1) from Amboina, Timor, 

 Matuka, and Mauritius, aud by myself (5) from New Britain. 



Ceeebeatttlus coloratus Burger. 



A fragment 9 cm. long and 1 mm. in diameter is probably to be 

 referred to this species, as the markings agree with the description 

 given by Burger (1). Unfortunately the anterior portion is 

 missing. 



Ceeebbatulus toreesianus, n. sp. (Plate LIV. figs. 1 a-e, 

 •3, & 6.) 



About 4 cm. of fragments including the anterior end, and having 

 an average width ofabout l'Smm. The head-slits measured 2-5mm.
