In Part I. of " Spolia RuniaDa," last year *, I dealt mainly with Hebridean 

 specimens of the giant Pennatiilid, Funicidina quadrangularis, and of the 

 Compound Ascidian Diazona violacea. During the cruise of the yacht 

 'Runa' in the present summer (July and August 1913), we were fortunate 

 enough to capture many additional specimens of both these comparatively 

 rare animals, and this Avealth of material has enabled me to add some further 

 particulars to what was previously recorded. During the cruise I paid 

 particular attention to the Tunicata, and preserved large numbers of several 

 common species with a view to studying individual variations and their 

 bearing on specific characteristics. We obtained also some specimens of the 

 less common Cynthiid Forhesella tessellata (Forb.), and the examination of 

 these has enabled me to offer some remarks upon the position of this isolated 

 species in the " system " of classification. 



The occurrence of a few other rare forms seems worth putting on 

 record :- — 



I. New OR Interesting Records. 



(1) The Starfish Pteraster [militaris (0. F. Miill.) was dredged in the 

 Inner Sound, between the Island of Raasay and the mouth of the Gair Loch 

 (Ross-shire), from a depth of 20 fathoms, on August 18th. This is a northern 

 species, found on the coast of Norway, and not previously known, I believe, 

 from the British seas — the nearest locality being the Faroe Channel, 

 ^ Porcupine ' expedition, from over 400 fathoms ; and, again, the ' Triton ' 

 expedition, 530 fathoms. 



Prof. Jeffrey Bell in a letter (Oct. 22nd) remarks : " I do not suppose it 

 occurs in strictly British waters.'-* Consequently the present record makes 

 an addition to the known British Fauna, 



Our Scottish specimen measures as follows : — • 

 R = 22 mm. r = S mm. 

 Greatest height = 8 mm. 

 Breadth of arm at base = 10 mm. 



A red eye-spot is conspicuous at the extremity of each arm.
