594 SUBANTARCTIC ISLANDS OF NEW ZEALAND. [Pisces. 



Boulenger has indicated by means of footnotes his conception of the synonymy 

 of the many species of Notothenia. According to these notes, the New Zealand species 

 are as follows : — • 



1. N. coriiceps, Rich., Voy. Ereb. & Terr., Fishes, 1844, p. 5, pi. iii. 



2. N. colbecki, Boul., Rep. " Southern Cross," 1902, p. 185, pi. xvi. 



3. N. microlepidota, Hutt., Trans. N.Z. Inst., viii, 1876, p. 213. 



4. N. macrocephala, G-iinth., Cat. Fish. Brit. Mus., ii, 1860, p. 263. 



5. N. filholi, Sauv., Bull. Soc. Philom. (7), iv, 1880, p. 228.

The species was first described from examples collected, at Campbell Island. In 

 February, 1907, while on a tour of the southern islands by kind invitation of His 

 Excellency the Governor, I found it to be quite common at Antipodes Island. While 

 at anchor on the north-east side of the island I put lines over and caught this " cod " 

 very readily. It affords no sport, and is hauled unresistingly to the surface. Many 

 of the fishes were infested with fluke-like parasites, which glided over the surface 

 of the body; these and also internal worms have been examined by Professor W. B. 

 Benham, who identifies the former as species of Tristoma. The gills harboured 

 crustacean parasites which Dr. Chilton identifies as Livoneca novae-zealandiae, 

 Miers, a common parasite of New Zealand fishes. The presence of these varied 

 parasites renders the fish most uninviting, and no one on board thought of 

 asking the cook to supply fresh fish. All the specimens caught were larger 

 than the Campbell Island examples taken by the "Southern Cross" Expedition, 

 the maximum being 515 mm.. Either this or an allied species attains gigantic 

 dimensions, for a headless and otherwise mutilated fish " apparently closely 

 allied to N. colbecki'' was obtained by members of the National Antarctic Expe- 

 dition, 1901-4, at the winter quarters. The remains of this specimen measured 

 1,170 mm.* 



The only specimen obtained by members of our Campbell Island party was 

 preserved by Professor Kirk. It was secured at Perseverance Harbour, among 

 stones, at low water. I netted a small specimen in the seine at Musgrave 

 Harbour, Auckland Islands, these two being the only ones taken, during the 

 expedition. 



The following is a description of one of the Antipodes Island specimens : — 



B. VI ; D. VII, 28 ; A., 23 ; V. I, 5 ; P., 21 ; C, 13 + 17. Scales— Long., 102 ; 

 tr., 13+38; lin. lat., 72 + 33. Vert., 19 +26 = 45. 



Length of head, 3*4 ; height of body, 4-6 ; length of caudal, 7*0 in the total 

 length ; diameter of eye 5'6 ; interorbital width 3-1 in the length of the head. The 

 maxillary extends to below the first third of the eye ; the lower jaw is longer than 

 the upper. The gill-membranes are wholly attached to the isthmus, and the gill- 

 rakers are rather short, 22 in number on the first arch, 15 of which are on the lower 

 limb. Pseudobranchiae well developed.
