314 REPORT 1868. 



Asterias glacialis, Linn. Often brought up on the hooks of the long lines, 

 from the Middle Haaf, Out Skerries. 



Mulleri (Sars). Added to the British fauna in 1861, when this pretty 



species was dredged off the Whalsey Skerries. It is very local. 



rubens, Linn. 



viola cea, Miiller. 



hispida, Pennant. I am inclined to think that this and the two pre- 

 ceding must be united. A. hispida was taken under stones between tide- 

 marks at the Out Skerries. 



Order ECHINOIDEA. 



Echinus esculentus, Linn. = J T . sphcera, Forbes. Between tide-marks and in 

 the laminarian and coralline zones. 



Yar. tenuispina. AnEchinus was found in 1863 which must be regarded, 

 I think, as a remarkable deep-water variety of esculentus. In form it 

 is very high in proportion to its breadth, and the diameter is not at all 

 greater below than above. The whole outline is perfectly free from any 

 appearance of angularity in any part, and the spines are remarkably 

 slender and delicate. 'It was brought up from a hard bottom 25-30 

 miles north of Unst, in 110 fathoms, and has a totally different 

 appearance from the shallow- water forms of the species. 



Flemingii, Ball. Outer Haaf, frequent ; but the specimens smaller and 



also wider in proportion to the height than those from the south. One 

 of the largest Shetland specimens measures three inches high and four 

 wide. 



miliaris, Leske. Common, tide-marks and Yoes, and also in deep water. 



norvegicus, Diiben & Koren, Ofversigt af Skandinav. Echinodermer, 



p. 268, pi. ix. figs. 33-39. Gregariously abundant ; in immense pro- 

 fusion on the Outer Skerries Haaf, 40 miles east of Whalsey Lighthouse ; 

 comparatively scarce on the Unst Haaf; St. Magnus Bay frequent. The 

 bulk of specimens procured do not exceed three-fifths of an inch in dia- 

 meter; one specimen, however, measures 1^- inch. The spines are 

 generally more or less of a green colour ; but a beautiful variety also 

 occurs in which they are vermilion-red, tipped with white.

 Sound. 



pictus,!!. sp. Ambulacral pores in 4 or 5 pairs; ambulacral plates 



with one primary and many very small tubercles. Interambulacral 

 plates also with only a single primary and numerous very small tu- 

 bercles. Spines banded red and white. Diameter of a large specimen 

 1| inch. In deep water, Shetland Haaf, scarce, and dredged in 40 fa- 

 thoms, near the Feme Islands, on the Northumberland coast. It is 

 also among the Echinodermata dredged by Messrs. Carpenter and 

 Thomson in the ' Lightning ' expedition during the past autumn in 

 lat. 60 28' N. long. 6 54' W. in 500 fathoms, stones and mud, and a 

 temperature of 32. 



Distinguished at a glance from Drbbachiensis by its more slender 

 spines and their coloration, which in the latter species is green or 

 purple, or a mixture of those two colours and white. When the spines 

 are cleared off, the shell is found to differ in having only one primary 

 tubercle to each interambulacral plate, while in Drbbachiensis there are
