310 CHILTON 
Several specimens taken on fish at Station 6,° off Stewart 
Island. The species is a common parasite on several species of 
fish in New Zealand seas, and is widely distributed in southern 
seas. Thielemann records it from Yokohama also. 
Though I had previously hesitated, I now think that our New 
Zealand species should be referred to ZL. raynaudi Milne- 
Edwards from the Cape of Good Hope, as has already been done 
by Mr. Whitelegge, Schiddte and Meinert give L. nove-zealandie 
as a doubtful synonym of L. raynaudii; they examined Milne- 
Edwards’ type specimen and included with it specimens from 
New Zealand and Australia. Dr. W. T. Calman of the British 
Museum, who has kindly looked into the question for me, informs 
me that the only South African specimen of the genus in the 
Museum is one from ‘‘Simons Bays,’’ identified (apparently by 
Miers) as L. nove-zealandiw; further, Dr. Calman has compared 
Miers’ type specimens of L. nove-zealandie with Schiodte and 
Meinert’s figures without detecting any obvious differences. 
EXOSPHAEROMA CHILENSIS (Dana). 
Spheroma chilensis Dana, U.S. Explor. Exped. Crust, 1853, 
Ds 111, ple lites Saze, 
Spheroma chilense Hansen, Q. Jour. Micro. Sci. xlix., 1905, 
p. 116. 
There are three specimens from the Chatham Islands which I 
think undoubtedly belong to this species. Dana described the 
species as follows :— 
‘Body smooth. Abdomen with two obsolete prominences 
above, caudal segment short, very broadly rounded behind. 
Caudal stylets reaching just to line of extremity of abdomen; 
inner lamella arcuate on outer side, sub-acute at apex; outer, 
straight lanceolate, round at apex.’”” 
The specimens agree well with the brief description given by 
Dana, except that I should be inclined to describe the posterior 
end of the pleon as truncate with rounded angles rather than 
‘‘very broadly rounded.’’ This, however, is a character that 
appears to vary according to the size, the posterior extremity 
being distinctly truncate in larger specimens while in smaller 
ones it could quite well be described as very broadly rounded. 
Though this species has not been previously recorded from 
New Zealand it is widely distributed on the New Zealand coasts, 
and I have for some time had in my collection specimens from 
(6) The only fishes taken at Station 6 were :—Physiculus bachus, Thyrsites 
atun, Clupea neopilchardus, and Pelotretis flavilatus. ED.

for a copy of this description; the text of Dana’s report is not available in 
Christchurch.
