ON THE SHETLAND CRUSTACEA, 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. 

 Galaihea dispersa, Bate. Abundant. 

 Munida Bamffia (Pennant) (M. Rondeletii, Bell). 

 Homarus yammarus (Linn.). 

 Ci-anyon vidyarus, Eabr. 

 Allmanni, Kinahan. Everywhere in deep water. It is unquestionably 



distinct from the last, which never occurs in deep water. 



fasciatus, Eisso. Five specimens, 1868. 



nanus, Kroyer (G. 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. 



spinosus, Leach. Common. 



serratus, Norman, Brit. Assoc. Report, 1861 (1862), p. 151 = (7. echi- 

 nulatus, M. Sars, Yidenskabs Selsk. Porhandl. 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. 



Salrincea septemcarinata ^Sabine). The only known British example was 

 dredged, in company with the last, in 80-90 fathoms, in 1861. 



Nilca edidis, 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. smaraydina, Kroyer). 



pusiola, Kroyer (H. Andrewsii, Kinahan, H. Barleii, Bate). 



C ranch ii, Leach. Rare, and only the variety with the extremity of 



rostrum trifid ( = ZT. mutila, Kroyer = 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 

 1 * 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 Thompsons, Bell, Panddlus Jeffreysii, 



Bate). Very common, 



Palcvmon 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.
