328 Part III. — Eighth Annual Report 



The one that seems to be the female differs from that now described 

 chiefly in the following points : — The flagellum of the antennules is 5- 

 jointed, the first and second joints rather shorter than the others (figs. 10-11). 

 The flagellum of the antennae is 10-jointed; the first joint is moderately 

 l 011 g — longer than the next two together, which are short, and about equal 

 in length, fourth joint rather longer than the preceding; the remaining 

 joints gradually increase in length, and become more slender (fig. 11). 

 The inner joint of the posterior pleiopods, which is also 1-jointed, is 

 rather longer than, and as stout as the first joint of the outer branch; the 

 two forms are very much alike otherwise. 



Habitat. — Off St Monance, in 12 to 15 fathoms, not very common. 



Amphitkopsis latipes (M. Sars). 



Calliope ossiani, Bate and Westwood, Brit. Sess.-eyed Crust., vol. 



i. p. 261 (1868). 

 Calliope fing alii, idem ibidem, vol. i. p. 263. 

 Ampkitkopsis latipes, Norman, Mus. Norm., part iii. p. 15 (1868). 



Habitat. — Several specimens attached to a Zoophyte (Antennularia) 

 brought up in the trawl-net a few miles east of Inchkeith; they were, 

 with one or two exceptions, all prettily marked by brown bands ex- 

 tending from the side along the posterior edge of each segment of the 

 posterior pleon; the coxse were also of the same colour. In the form of 

 the antennules and antennae, and of the gnathopods and in the coloration, 

 they agreed with the form described by Spence Bate as Calliujje ossiani. 

 The Rev. T. R. R. Stebbing, to whom I submitted specimens, and who 

 corrobated my diagnosis, informs me that Boeck and Norman identify 

 Calliope ossiani and C. fingalli, Bate and Westwood with Amphitkopsis 

 latipes (M. Sars). I have therefore followed them in ascribing my 

 specimens to Sars's species. 



Epimeria cornigera (Fabricius).

Habitat. — East of Inchkeith, about 3 miles. The colour of this pretty 

 species is white, somewhat pellucid, beautifully variegated with bright 

 red; the postero-lateral margins of each segment is of this colour, which is 

 also more or less diffused over the dorsal surface. I have also got this 

 species in the Moray Firth ; and Mr Robertson records it from various 

 places in the Clyde district.

Siphonoecetus colletti (?), Boeck.

p. 178. 

 Siphonoecetus colletti, idem, De Skand. og Arkt. Amph. (1876), p. 



633, pi. xxviii. fig. 9. 



Habitat. — Largo Bay, frequent. New to Britain. It is quite possible 

 that this may have been passed over as a Corophium, otherwise it is diffi- 

 cult to account for its not being previously recorded. The specimen comes 

 very near to S. typicus, and it may ultimately be found to belong to that 

 species. I prefer therefore to consider it for the present as doubtful.
