274 REPORT 1868. 



margin, both towards the base and towards the finger, at this point 

 the elongated lobe of the wrist terminates and the palm begins ; this is 

 gently arched, sloping away to the base of the claws, with the margin 

 denticulately serrated throughout (no spines or larger teeth) ; finger as 

 long as the palm, slender, curved correspondingly to the palm. First 

 and second pereiopods slender., propodos and nail long. Last pereiopods 

 having the metacarpus infero-posteally produced (as is usual in the 

 genus) to half the length of the wrist ; no portion of the limb serrated. 

 Length one-twelfth of an inch. One specimen, dredged in about 50 

 fathoms in St. Magnus Bay, 1867. Probolium polyprion, Costa, agrees 

 with the present species in having a serrated palm to the second 

 gnathopods, but differs in the form of the hand, and the presence of spines 

 at the distal extremity of the palm, in the wrist not being produced, 

 and in the anterior margin of the last pair of pereiopods being serrated. 



Probolium pollexianum (>&to}=Montaguapollexiana, Bate & Westwood. 58 

 miles east of Balta in 50 fathoms ; apparently rare in Shetland, one 

 specimen only having been found. 



Lysianassa Gostce, M.-Edwards. Scarce. 



Audouiniana, Bate. A specimen taken among Laminaria3, 3-5 fathoms, 



Out Skerries Harbour, in 1861, and then submitted to Mr:' Bate, was 

 considered by him to be a " black-eyed variety " of this species. 



longicornis, Lucas. One specimen, 20-25 miles north of Burrafirth 



Lighthouse in 1863. 



Anonyx longicornis, Bate. A few specimens, deep water, St. Magnus Bay. 

 This species is recognized instantly by the peculiar dorsal and lateral 

 angles of the body, and the curious hooded form of the large first joint 

 of the superior antenna.

Dredged in deep water, St. Magnus Bay, 1867. New to Britain. I 

 have received it also from Mr. D. Eobertson, who took it in the surface 

 net in the Firth of Clyde; and from Mr. Laughrin from Polperro, 

 where it would seem to be remarkably abundant.
