B22 REPORT—1868.. 
Filellum serpens (Hassall) = Reticularia serpens. The generic title Reticularia 
being preoccupied, Mr. Hincks substitutes /ilellum for it. Creeping on 
the stems of Sertularie, &c., in the Burrafirth caves. 
Lafoéa dumosa (Fleming). 
fruticosa, Sars=Campanularia gracillima, Alder. Rare, Outer Haaf, 
off Whalsey Skerries, and 5-8 miles off Balta, 40-50 fathoms, 
Calycella syringa (Linn.). ‘Shetland, 1858, Barlee ” ( fide Alder in litt.). 
fastigiata, Alder, Ann, Nat. Hist. 3rd ser. vol. v. 1860, Feb. pl. v. 
fig. 1. Described from specimens procured by Mr. Barlee in 1858 ; 
again found by myself in 1863 and 1867, creeping on the stems of the 
larger Hydrozoa. 
Ouspidella humilis, Hincks, Ann. Nat. Hist. Oct. 1866, p. 298. Found by 
Mr. Hincks and myself on stems of Zoophytes. 
grandis, Hincks. ‘ A new species which has occurred in some dredg- 
ings from Connemara of G. §. Brady’s, and in Shetland, teste Mr. Alder. 
I do not know the history of the specimens, but you know the accuracy 
his labellings ” (Hincks in litt.). 
Campanularia flecuosa (Hincks)=Laomedea flewuosa. Common, between 
tide-marks, on Fuci. 
neglecta (Alder). Rare, Unst. 
volubilis (Linn.). On Laminariz, in Bressay Sound, in 3-5 fathoms.

water, in the Burrafirth caves.

Clytia Johnstoni (Alder). Bressay Sound and Unst. 
Obelia longissima (Pallas). 5-10 miles east of Balta, in 40-73 fathoms. 
geniculata (Linn.). I insert this species with doubt. In the MS. list 
of species procured in 1861, I entered “ Laomedea geniculata, var.” as 
common on Laminariz in Bressay Sound. I have not specimens pre- 
served, and they may perhaps have belonged to one of the forms lately 
elevated to specific rank. 
gelatinosa (Pallas). The specimen from which Johnston’s plate xxvii. 
was drawn was procured by Dr. Coldstream in Shetland (wide p. 105). 
—— plata, Hincks. ‘One of the new species I met with in the large 
bottle of Shetland Hydrozoa sent me by Mr. Jeffreys. The precise 
place was not marked on it. This Obelia is a very splendid one”

cornea, 8. Wright. With C. multicornis, at Lerwick, in 1861. Ex-
