keep the species apart, notwithstanding a very 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 seise. 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 seta3. 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. 



Bafhyporeia 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 proximo., Bate & Westw. Brit. Sessile- 

 eyed Crust, p. 344 (the more common variety of male), Megamcera 

 Alderi, Bate & Westwood, p. 407 (the female). St. Magnus Bay, off 

 Balta, Outer Haaf, &c. 



Melita proximo, is the common form of the male, and Meg ameer a 

 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. 



Mcera longimana (Leach) = Megamcera longimana, Bate & Westw., the male 

 = Megamcera othonis, Bate & Westw., the female. St. Magnus Bay, both 

 sexes. 



brevicaudata (Bate) = Megamcera brevicaudata, B. & W. A specimen 



determined by Mr. Bate, dredged in 4 fathoms, Bressay Sound, 1861. 



Eurysitieus erytlirophtlialmus (Lilljeborg). 5-8 miles off Balta, 40-50 fathoms. 



AmatJiilla Sabini (Leach). Tide-pools, frequent. 



Gammarus marinus, Leach. Between tide-marks. 



campylops, Leach. " Our friend the late Mr. Barlec sent us some from 



the Shetlands " (Bate and Westwood). 



locusta, Linn. 



pulex, Linn. 



Heiscladm 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. 



Ampliithoe rubricata (Montagu). 



littorina, Bate. 



albomaculata, Kroyer. The only known British specimen, dredged in 



1861, sixty miles east of Shetland, in 70-90 fathoms.
