ON THE SHETLAND CRUSTACDA, TUNICATA, ETC. 265 
enable me to identify it with the British G. Andrewsii, and to correct 
an error I had fallen into in considering it, from his description, to be 
synonymous with G. dispersa, Bate. 
Galathea dispersa, Bate. Abundant. 
Munida Bamffia (Pennant) (M. Rondeletii, Bell). 
Homarus gammarus (Linn.). 
Crangon vulgarus, Fabr. 
Allmanni, Kinahan. Everywhere in deep water. It is unquestionably 
distinct from the last, which never occurs in deep water. 
fasciatus, Risso. Five specimens, 1868. 
nanus, Kroyer (C. bispinosus, Hailstone). 5-8 miles east of Balta, 
40-50 fathoms, common; also Whalsey Skerries Haddock ground, and 
occasionally elsewhere. 
trispinosus (Hailstone). One specimen near Balta, 1863. 
——- spmosus, Leach. Common. 
serratus, Norman, Brit. Assoc. Report, 1861 (1862), p. 151=C. echi- 
nulatus, M. Sars, Videnskabs Selsk. Forhandl. i Christiania, 1861, p. 186. 
This species was discovered by Prof. Sars and myself about the same 
time. In 1861 two specimens were taken sixty miles east of Shetland ; 
it was not again. procured in Shetland until 1867, when it was met 
with in St. Magnus Bay, 
Sabina septemcarinata (Sabine). The only known British example was 
dredged, in company with the last, in 80—90 fathoms, in 1861. 
Nika edulis, Risso. Very local ; abundant in one day’s dredging, 25 miles N. 
by E. from Unst, 90-100 fathoms, 1863; St. Magnus Bay, 1867. 
Doryphorus Gordoni, Bate. Deep water, very local. 
Hippolyte varians, Leach (H. smaragdina, Kroyer). 
pusiola, Kroyer (H. Andrewsti, Kinahan, H. Barleii, Bate). 
Cranchit, Leach. Rare, and only the variety with the extremity of 
rostrum trifid (=H. mutila, Kréyer = H. Yarrellii, Thompson). 
pandaliformis, Bell. Very fine; abundant in the West Voe, Whalsey 
Skerries, 1861; also Balta, 1863, and Hillswick, 1867; always in 
laminarian zone. 
—— securifrons, Norman. Not uncommon in deep water. 
—— cultellata, Norman, Brit. Assoc. Report, 1866 (1867), p. 200. Two 
specimens 40 miles east of Whalsey Skerries in 1861, then recorded as 
“ H. polaris.” There are certain particulars, however, in which Kroyer’s 
description does not accord with the British form, though an actual 
comparison of specimens may hereafter prove them to belong to the 
same species. 
Pandalus annulicornis, Leach. 
—— brevirostris, Rathke (Hippolyte Thompsoni, Bell, Pandalus Je reystt, 
Bate). Very common. 
Palemon squilla (Linn.). Tidemarks, Lerwick, rare, 1861. 
Order STOMAPODA.

Report British Association, 1861 (1862), p. 151. One specimen, Outer 
Haaf, Whalsey Skerries, in 1861; a second, Unst Haaf(?), 1868. This 
species, described by me in 1861, was the subject of a most elaborate 
monograph by Professor Sars in the following year.
