260 REPORT—1868. 
WEL. 
Species peculiarly characteristic of the Fauna of the Outer Haaf. 
The following list gives the species which impart a peculiar character to 
the fauna of the deep sea of Shetland, known as the “ Outer Haaf,” in a 
depth of 80-170 fathoms. The Molluscan inhabitants of this region are 
highly interesting, but it is not within my province here to speak of them. 
Crustacea are few in numbers, Portunus tuberculatus, Munida, two or three 
species of Orangon, Pandalus brevirostris, Cumacea, Ampelisca, and Epimeria 
tricristata being the most abundant. Echinodermata are abundant, and cer- 
tain species sometimes in tie most extraordinary profusion. Polyzoa and 
Sponges are very abundant, but of Coelenterata there are but few species; 
those species which do occur belong, for the most part, to the Zoantharia. 
Caryophyllia Smithii var. borealis is found inhabiting these depths in 
marvellous abundance; Zoanthus anguicoma is common, creeping over 
Sponges from the greatest depths, and an occasional Bulocera eques or 
Tuedic, or a noble Ulocyathus areticus presents itself to our admiring gaze, 
Very few Tunicata occur below seventy fathoms. 
The names which follow are of the most abundant or, at any rate, more 
conspicuous species; the list might, had I so wished, haye been greatly 
extended.
