B. appendiculata Steenstrup and Lutken, 1861, p. 419, and B. 

 appmdiculosa Bassett-Smith, 1898, p. 14, are both synonyms of 

 Thysanote appendiculata (see p. 651). 



B. dentata Wilson, 1912, p. 97, is proved by the structure of the 

 male to belong to the genus Oharopinus (see p. 654). 



B. Jtmbriata Heller, 1865, p. 240, belongs to the genus Thysanote 

 (see p. 651). 



B. gaini Quidor, 1912, p. 211, is placed with B. antarctica in the 

 new genus EubracliieUa (see p. 716). 



B. impudica Nordmann, 1832, p. 92, is proved by the structure of 

 the male as well as the female to be distinct from BmcJiiella and is 

 made the type of the new genus Epihracliiella (see p. 715). 



B. inconcinna, minuta, and ramosa were simply named by Richiardi 

 (1880, p. 151) and have never been described or figured. 



B. insidiosa Heller, 1865, p. 239, is referred to the new genus 

 Parabrachiella (see p. 713). 



B. lohiventris Heller, 1865, p. 241, belongs to the genus Thysanote 

 (see p. 651). 



B. lophii Mihie Edwards, 1840, p. 514, was briefly described and 

 well figured, but has never been seen by any other investigator, 

 although it is included in two or three lists on the authority of Milne 

 Edwards. The description and figures given by the latter are enough 

 to indicate fairly well that the species does not belong to Brachiella, 

 nor indeed to any of the other genera in the family. 



The size of the creature (cephalothorax and second maxillae 20 

 mm.; trunk and posterior processes 16 mm.), the structure of the 

 second antennae, first maxillae (unipartite) , and maxilHpeds, and the 

 peculiar shape and attachment of the posterior processes show httle 

 afFmity with any of the genus types here presented. 



But the male is unknown and the data are not sufficient to enable 

 us to erect a new genus, so the best that can be done is to leave it 

 where Milne Edwards placed it and wait for further details. 



B. malleus Nordmann, 1832, p. 95, is proved by the structure of 

 the male, as well as certain characters of the female, to belong to the 

 genus Oharopinus (see. p. 654). 



B. multijimhriata Bassett-Smith, 1898, p. 96, is shown by the struc- 

 ture of the male to be distinct from Brachiella, and as the female is 

 also pecuhar it is made the type of a new genus, Thysanotella (see 

 p. 652). 



B. neglecta Richiardi, 1880, p. 151, was another mere name, but it 

 was afterwards briefly described and figured by Brian (1898. p. 24, pi. 

 4, fig. 29). He, however, mentions and portrays a pair of tubercles, 

 each armed ^vith a claw, on the posterior margm of the trunk. Noth- 

 ing like them is known anywhere among the Lernaeopods, and if cor- 

 rect the parasite would at least become a distinct genus. But it has
