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 band, 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 (Bate)= Montagua pollewiana, Bate & Westwood. 5-8 
miles east of Balta in 50 fathoms; apparently rare in Shetland, one 
specimen only haying been found, 
Lysianassa Coste, M.-Edwards, Scarce. 
—— Audoumiana, Bate. A specimen taken among Laminaria, 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 antenne.

Dredged in deep water, St. Magnus Bay, 1867. New to Britain. I 
have received it also from Mr. D. Robertson, 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,
