310 Part III—Ninth Annual Report 
AppiT1onaL Norrs.——Since the preceding notes were in the hands of 
the printer I have been enabled to add the following species, the Rev. 
A. M. Norman, F.R.S., having kindly named them for me. 
Caligus isonyx, Steenstrup and Liitken. 
Habitat.—Inside the gill-covers of the common gurnard (Trigla gur- 
nardus). I find this Caligus of frequent occurence on specimens of the 
ommon gurnard taken by us in the Forth, but on no other kind of fish. 
Hexmobaphes cyclopterina, Fabr 
Habitat.—Attached to the gills of the pogge (Agonus cataphractus). 
This interesting species was obtained by Mr Peter Jamieson, Assistant 
Naturalist to the Fishery Board, adhering to the gills of a pogge taken 
from the stomach of a cod at Dunbar, during April of this year (1891). 
Dr A. M. Norman informs me that this is the first time Haemobaphes has 
been observed in the British seas. The arrangement of the ovaries differs 
from that of all other species with which I am acquainted. Each ovary 
resembles a coiled-up rope, the coils being of equal diameter throughout, 
' and resting the one on the other, thus forming a miniature cylinder. 
The length of the parasite, including the ovaries, is fully half an inch. 
Charopinus Dalmanni, Retzius. 
Habitat.—Attached to the inside of one of the spiracles of a large grey 
skate (Rava batis) caught by the ‘Garland’s’ trawl 8.E. of May Island. 
This is a large species. The specimen obtained measures about 2 inches 
in length, including the ova-sacs. 
Tauria medusarum (O. Fab.), | Hyperia tauriformis, Bate and West- 
wood, Brit. sess.-eyed Crust., il. p. 519 (1868)]. Taken with the surface 
tow-net in the vicinity of the Bass Rock, November 1890. Several 
specimens were obtained. Both gnathopods of this species are chelate, 
the lower part of the carpus being produced forwards so as to reach the 
extremity of the propodos. ‘The inner margins of the produced part of 
the carpus and of the propodos is serrated. This species was first 
obtained in British waters by Thomas Edward of Banff.
