ON THE SHETLAND CRUSTACEA, TUNICATA, ETC. 281 
thoms; forty miles east of Whalsey Skerries, 70-90 fathoms. The 
name Calliope being preoccupied, Lilljeborg has changed the title of 
this genus to Calliopius. 
Calliopius Fingalli (Bate & Westw.). The type specimen found in 1861. 
Eusirus Helvetie, Bate=Husirus bidens, Heller, Amphip. des adriatischen 
Meeres, p. 32, pl. iii. fig. 19. Five to eight miles east of Balta, in 40-50 
fathoms, sand, 1867. Thighs of last three pereiopods strongly serrated 
behind; first two segments of pleon dorsally produced into a central © 
tooth; hinder margin of third segment of pleon serrated en the side, 
lower serrations directed upwards, upper serrations directed downwards ; 
all the uropods subequal in length; telson reaching to the middle of 
the rami of the last pair. 
Leucothoé furina (Savigny). St. Magnus Bay and Balta Sound. 
—— articulosa (Montagu). In branchial sac and water-passages of Ascidia 
mentula and A. venosa. This species and Anonyx tumidus are the two 
Amphipoda which, with a number of Copepoda, constitute the crustacean 
parasites of the Ascidiade. 
Gossea microdeutopa, Bate. Found in 1861; the exact habitat forgotten. 
Aora gracilis, Bate= Autonoé punctata, Bruzelius, Skand. Amphip. Gammarid. 
p. 24, pl. i. fig. 3. Common in shallow water in all the Voes, among 
Laminarie. The female differs widely from the male in the structure 
of the first gnathopods. In these organs the meros is not abnormal (as 
in male), the wrist subquadrate, slightly widening distally, posteriorly 
fringed with sete, and a tuft of setz on the side; propodos broadly 
ovate, with tufts of sete on both margins; palm undefined, except by 
the presence of a spine with which the finger when closed impinges ; 
finger strong, half length of hand, serrate on the inner margin, with a 
small cilium in each serration. I believe, judging from specimens named 
for me by Mr. Bate, and the figure and description which represent an 
animal ‘* sparingly scattered with black dots,” that the Microdeuteropus 
anvomalus of Bate and Westwood, p. 293 (not of Rathke), is the female 
of this species; but the females of this and of the next species are so 
very much alike as to be almost undistinguishable. 
Microdeuteropus anomalus (Rathke). Gammarus anomalus, Nova Acta Leop. 
1843, p. 63, pl. iv. fig. 7, =Autonoé anomala, Bruzelius, Skand. Amphip. 
Gammarid. p. 25, pl. i. fig. 4 (but scarcely Microdeutopus anomalus, 
Bate & Westwood, Brit. Sessile-eyed Crust. p. 289), =MWicrodeutopus 
gryllotalpa, Bate & Westwood, J. ¢. p. 289 (but not of Costa). 
The figure in the ‘ Brit. Sessile-eyed Crustacea’ of Microdeutopus gryl- 
lotalpa represents the young male of this species; in the adult male the 
strong tooth-like process of the carpus of the first gnathopods is itself 
furnished with a secondary (lateral) tooth ; and the hand is much nar- 
rower at the base than at the apex, the posterior margin being concave ; 
this state is well represented by Bruzelius, pl. i. fig. 4,d. The female 
is extremely like that of the last species, and is sufficiently well repre- 
sented at p. 293, Brit. Sessile-eyed Crust.; though, for reasons already 
stated, I incline to think that that figure really is drawn from the female 
of Aora. This species is most certainly not the Microdeutopus gryllo- 
talpa of Costa (Ricerche sui Crostacei Amfip. del regno di Napoli, 
p. 231, pl. iv. fig. 10), which, from the four teeth of the carpus, seems to 
be closely allied to, if not identical with the Autonoé grandimana of 
Bruzelius. Dredged in 70-90 fathoms, about forty miles east of the 
Out Skerries, 1861.
