322 REPORT 1868. 



Filellum serpens (Hassall) = Reticularia serpens. The generic title Reticularia 

 being preoccupied, Mr. Hincks substitutes Filellum for it. Creeping on 

 the stems of Secularise, &c., in the Burrafirth caves. 



Lafoea dumosa (Fleming). 



fruticosa, $&rs = Campanularia qracillima, 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. pi. 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. 



Cuspidella 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. S. 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 flexuosa (Hincks) = Laomedea flepuosa. Common, between 

 tide-marks, on Fuci. 



neglecta (Alder). Eare, Unst. 



volubilis (Linn.). On LaminariEe, in Bressay Sound, in 3-5 fathoms. 



integra (Macg.). Parasitic on Tubularia indivisa, at extreme low 



water, in the Burrafirth caves. 



vertidllata (Linn.) Rare, found in 1861.

 cured by Mr. Barlee in 1858. 



Cfytia Jolmstoni (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 Laminarias 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 (vide p. 105). 



plicata, 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 " 

 (Hincks in litt.).

hyalina, Hincks, Ann. Nat. Hist. Oct. 1866, p. 297. " Profusely in- 

 vesting Tubularia, Halecium, &c., from Shetland. I am indebted to J. 

 Gwyn Jeffreys, Esq., for my specimens " (Hincks, I. c.).
