310 Part III. — JMnth Annual Report 



Additional Notes. — Since the preceding notes were in the hands of 

 the printer I have been enabled to add the following species, the Kev. 

 A. M. Norman, F.R.S., having kindly named them for me. 



Galigus isonyx, Steenstrup and Liitken. 



Habitat. — Inside the gill-covers of the common gurnard (Trigla gur- 

 nardus). I find this Galigus of frequent occurence on specimens of the 

 ommon gurnard taken by us in the Forth, but on no other kind of fish. 



Hsemobaphes cyclopterina, Fabr 



Habitat. — Attached to the gills of the pogge (Agonus cataphr actus). 

 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 Hxmobaphes 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, Eetzius. 



Habitat. — Attached to the inside of one of the spiracles of a large grey 

 skate (Raia batis) caught by the ' Garland's ' trawl S.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., ii. 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.
