280 REPORT—1868. 
Odius carinatus (Bate). Otus carinatus, Bate & Westw. Brit. Sessile-eyed 
Crust. p. 224. Very rare; two specimens only, in 70-80 fathoms, 
sixty miles east of Shetland, 1861. The type was taken by Mr. Barlee 
in his last expedition to the Shetland Islands. The name Otus being 
preoccupied, Lilljeborg has substituted that of Odius for this genus 
(Lilljeborg, Crust. Amphip. Lysianas. p. 19). 
Helleria coalita, Norman, Ann. Nat. Hist. 4th ser, vol. 11, (Dec. 1868) p. 418.

Epimeria tricristaia, Costa, Ricerche sui Crostacei Amfipodi del regno di 
Napoli (1853), p. 197, pl. ii. fig. 2, = Acanthonotus Owenii, Bate, Brit. 
Assoc. Rep. 1855, p. 58; Bate and Westwood, Brit. Sessile-eyed Crust. 
p- 232. Common in deep water. This species is well described and 
figured by Costa, whose name must be adopted, since the specific name 
is four years prior to that of Bate; and as regards the genus, Acantho- 
notus being preoccupied among the Fishes, and Vertwmnus only a MS. 
title, we must also take that of the Italian naturalist. 
Dexamine spinosa (Montagu). Out Skerries Harbour, Lerwick and Balta 
Sounds, among Laminariz, always in shallow water. 
tenwicornis, Rathke. In similar localities to the last. 
—— Vedlomensis, Bate & Westwood. The type taken in Vidlom Voe in 
1861, since dredged in St. Magnus Bay, 60 fathoms; and 5-8 miles off 
Balta, 40-50 fathoms. 
Atylus Swammerdanut (M.-Edwards) = Amphithoé compressa, Lilljeborg, 
Ofvers. af K. Vet. Akad. Forhandl. 1852, p. 8. Bressay Sound and 
Hillswick, among seaweeds. 
gibbosus, Bate. An interesting species on account of the peculiar cha- 
racter of the carpi of the pereiopoda. It appears constantly to live 
parasitic in sponges (Halichondria panacea chiefly) between tide-marks 
and in shallow water. Abundant in Burrafirth Caves, also Balta Sound, 
Out Skerries Harbour, &c. 
bispinosus, Bate. St. Magnus Bay, in 50 fathoms. 
—— macer,n.sp. Pleon haying the posterior margin of the first five seg- 
ments serrated right across the back, with a larger central hastate 
tooth, which increases in size from the first to the fourth segment, 
where it attains its greatest development. All the members of the body 
unusually long and slender; pereiopods excessively long and delicate ; 
basos of posterior pairs narrow; meros and carpus both yery long, the 
former the longer, and both longer than the long propodos; nail very 
slender (half as long as propodos), with a single seta beyond the middle 
of the inner margin. Uropods very long, the last pair with peduncle 
and rami subequal, the whole organ as long as four segments of pleon 
(7. é. third to sixth). First gnathopods the longer, second the stouter ; 
in both pairs the hand shorter than wrist, and the palm undefined. 
Telson deeply sulcated. Length a quarter of an inch. St. Magnus 
Bay, muddy bottom, 60 fathoms, 1867. The eye in this species is 
situated unusually low down and opposite the base of the inferior an- 
tenne ; the antennee are broken off in my specimens. The slenderness 
of the anterior pereiopods is very remarkable. 
Pherusa bicuspis (Kréyer). Amphithoé bicuspis, Kréyer, Gronlands Amphip. 
p. 273, pl. ii. fig. 10. Balta Sound, 5 fathoms; and Bressay Sound, 
3-7 fathoms. 
— fucicola, Leach. Out Skerries Harbour, 3-5 fathoms, 1861.
