BemarJcs. — Tlie Hyperia faiiriformis of Sp. Bate & Westwood is un 

 doubtedly the same form, and as the specific name proposed by those authors _ 

 is the older one, it should take the precedence of that of Bovallius.

]{emarJcs. — The Themisto crassieornis of Kroyer is most probably this 

 species, and indeed the figure reproduced by Sp. Bate & Westwood of that 

 form agrees so very closely with that given in the present work, that I 

 cannot but believe both forms to be identical, though both Kroyer and Sp. 

 Bate represent the back as being quite smooth. But the dorsal processes are 

 often less conspicuous, and may thus have escaped the attention of the said 

 authors.

I have recently had an opportunity of examining this remarkable form 

 in the living state. During the summers of 1890 & 1891, I visited the Trond- 

 hjemsfjord for the purpose of investigating the fisheries, and by dropping the 

 fishing-line into deep water, I succeeded several times in procuring this 

 animal. It was in every instance found clinging to the skin of the common 

 black dog-fish (Spinax niger), and in most cases to the belly, near the anal 

 opening. It very easily detached itself from the fish, and swam about with 

 great agility. The body was of a pure white colour, with a slightly rosy tinge, 

 and exhibited along the back a ver}' conspicuous, beautiful orange tint, which,
