keep the species apart, notwithstanding a yery strong suspicion that 
they will hereafter prove to be the same. 
Protomedeia hirsutimana, Bate. Unst Haaf, 90-100 fathoms, and 5-8 miles 
east of Balta, 40-50 fathoms. The posterior portion of the body, un- 
known to Mr. Bate, has some very remarkable characters. The last 
three pereiopods successively increase in length, the apex of the palm is 
truncate, the finger is short, strong, and bifid, and takes its origin from 
one-half only of the end of the propodos, while from the other half 
spring several long, spine-like sete. First and second uropods sub- 
equal in length; the first with the branches furnished with the usually 
formed spines ; the second of most unusual and remarkable character, 
excessively strong and massive, the branches furnished on their upper 
edge with two rows of immensely strong, but very short, stout, blunt 
spines; last uropods shorter than preceding pairs; branches subequal 
to peduncle, each bearing about three strong spines and terminating in 
a tuft of sete. Telson tubular. 
The extraordinarily massive and immensely strong spined second 
uropods have no parallel, as far as I am aware, among the known 
species of Amphipoda. 
Bathyporeia pilosa, Lindstrom. Forty miles east of Out Skerries, 70-90 
fathoms ; 5-8 miles east of Balta, 40-50 fathoms; Balta Sound, 5-7 
fathoms. 
—— Robertsoni, Bate. “Two specimens have been dredged by our friend 
Mr. J. Gwyn Jeffreys in the Shetlands” (Bate and Westwood). 
Melita obtusata (Montagu) = Melita proxima, Bate & Westw. Brit. Sessile- 
eyed Crust. p. 344 (the more common variety of male), = Megamera 
Alderi, Bate & Westwood, p. 407 (the female). St. Magnus Bay, off 
Balta, Outer Haaf, &e. 
Melita prowima is the common form of the male, and Megamara 
Alderi is the female. The variety of the male with a central dorsal 
tooth on the second and third segments of pleon is far less common, 
and is the typical Melita obtusata (Mont.); one specimen of this variety 
has occurred to me in Shetland, and other specimens show scarcely 
visible rudimentary teeth on those segments. 
Mera longimana (Leach)=Megamera longimana, Bate & Westw., the male 
= Megamera othonis, Bate & Westw., the female. St. Magnus Bay, both 
sexes. 
brevicaudata (Bate)=Megamera brevicaudata, B. & W. A specimen 
determined by Mr. Bate, dredged in 4 fathoms, Bressay Sound, 1861. 
Lurystheus erythrophthalmus (Lilljeborg). 5-8 miles off Balta, 40-50 fathoms. 
Amathilla Sabini (Leach), Tide-pools, frequent. 
Gammarus marinus, Leach. Between tide-marks. 
—— campylops, Leach. “Our friend the late Mr. Barlee sent us some from 
the Shetlands” (Bate and Westwood). 
—— locusta, Linn. 
pulex, Linn. 
Heiscladus longicaudatus, B. & W. The type specimens were taken in 1861, 
in 2-5 fathoms, Out Skerries Harbour; also St. Magnus Bay, and Balta 
and Bressay Sounds. 
Amphithoé rubricata (Montagu). 
—— littorina, Bate. 
—— albomaculata, Kroyer. The only known British specimen, dredged in 
1861, sixty miles east of Shetland, in 70-90 fathoms.
