Ophionemertes agilis (Ver.), Gr'd::=Aniphiporus agilis Yer., vol. viii, p. 400. 



In the paper last quoted, I have made Ophionemertes a subgenus 

 or section of Amphiporus, including the slender, very active species, 

 with many eyes on each side of the head, in linear series. 



Ophionemertes Stimpsoni Gr'd, p. 27 7= Amphiporus angulatus Yer., vol. 

 viii, p. 390. 



This species is also enumerated by Girard under the name of Cos- 

 mocephala Stimpsoni^ on p. 250. Its synonymy is fully explained 

 in my former article. It does not belong to the subgenus Ophione- 

 mertes. 



Astem.m.a resplendens Gr'd, p. 279=Am.phiporus caecus Yer., vol. viii, p. 402. 



Dr. Girard knew this species only from my brief mention of it in 

 1873, under the designation '■^ Kemertes (?) sp. undet., a." 



Astem.m.a coUaris Grr'd=:?Am.phiporus caecus Yer., young. 



This name was applied by Dr. Girard to the form designated by 

 me as " JSTemertes (?) sp. undet., />." It was very young (8°^™), and 

 only imperfectly observed. 



Micrura affinis Gr'd, p. 280=Do., Yerrill, vol. viii, p. 428. 

 This is identical with Poseidon affinis Gr'd, p. 258. 



Micrura inornata Yer. ; Gr'd, p. 281=:Do. Yer,, vol. viii, p. 431. 

 Micrura albida Yer.; Gr'd, p. 281=Do. Yer., vol. viii, p. 431. 

 Am.phiporus virescens Yer.; Gr'd, p. 282=N'em.ertes Verrillii Gr'd, p. 274. 

 Am.phiporus roseus (Miill.) Yer. ; Gr'd, p. 282 = Do. Yer., vol. viii. 395. 

 Amphiporus cruentatus Yer.; Gr'd, p. 2 83 = Do. Yer., vol. viii, p. 399. 



The five preceding species are taken from my former paj^ers, with- 

 out change. 



Hallezia Gr'd, (new name)=Dichilus Stimp. 



This name is proposed for a subdivision of Am2)hiporus (types 

 A. hastatus and A, bioculatus Mclnt.). It is essentially identical 

 with Dichilus Stimp. and Naredopsis Verrill (see vol. viii, p. 389). 



Hallezia hastata Gr'd, p. 284, in part = Amphiporus caecus Yer., vol. viii, 



p. 402. 

 H. bioculata Gr'd, p 285= A. (Naredopsis) bioculatus ? Yer., vol. viii, p. 401. 

 Neesia Gr'd, p. 286, superfluous new name=Nemertes Mclnt, (not of earlier 



authors) =Emplectonema Stimp., 1857=Macronemertes Yer., 1873=Eune- 



mertes Yaill., 1885. (See above, p. 528.)
