to its hosts. I have seen specimens from Lyttelton, Duuedin, 

 and Greymouth, those from the latter locahty being forwarded 

 to me by Mr. E. Hehns. Mr. Thomson also records the 

 species from the west coast of the South Island. Schiodte 

 and Meinert had specimens from Melbourne also. 



It is hazardous to venture opinions on the affinities of 

 different species from descriptions alone ; but, so far as I can 

 tell from those of the species described by Schiodte and 

 Meinert, the one that comes nearest to our species is N. 

 duviatilis from the Eio Plata — a species which is perhaps the 

 same as one found at the Falkland Islands.

In this paper I propose dealing with the most important 

 features in the general anatomy of our New Zealand Eed 

 Cod {Lotella bacchus). The original paper, which was written 

 last year as a thesis for the honours examination of the New 

 Zealand University, contains a quantity of matter which it 

 has been deemed advisable to omit. This matter was simply 

 a restatement and verification of the facts, in the anatomy of 

 other Teleosteans, so well stated in our usual text-books, and 

 therefore superfluous in a paper such as the present. 



Lotella bacchus. 



External Characters. — Form of lateral-line scales. Variation 



in tin formula. 

 Skeleton. — Articulation of dermal-fin rays with interspinous 



bones. Symmetrical tail. Cartilaginous parts of cranium.
