B24 REPORT—1868. 
edge of the operculum of Turritella communis, dredged in Basta Voe, 
Shetland. Out of between twenty and thirty specimens of living Tur- 
ritella examined, not one was free from this remarkable little Zoophyte ” 
(Allman). Mr. Hincks tells me that he has identified this species with 
Perigonimus repens, Allman, but that Prof. Allman dissents, This being 
so, I think it better to retain here the name of minutus given to the 
Shetland specimen. 
Garveia nutans, 8S. Wright= Zudendrium (Corythamnium) baceiferum, All- 
man. ‘Very fine, amongst a number of Zoophytes from Shetland, sent 
me by Mr. Busk. In the bottle containing it was also the Coryne ver- 
micularis, Hincks, and Zoanthus incrustatus, which I am glad to see you 
recognize as a distinct species. I have taken the same view in my Devon 
Catalogue, in a note on Cellepora edax. I do not know the precise 
locality in which these things were found ” (Hincks in litt.). 
Dicoryne conferta, Alder. Abundant on shells, especially of Aporrhais pes- 
pelecani, dredged in 40-50 fathoms 5-7 miles off Balta, and in St. Mag- 
nus Bay. 
Tubularia indivisa, Linn. In great abundance at low water, spring tides, in 
the Burrafirth caves, also dredged in 50-60 fathoms.

Assoc. Rep. 1862 (1863), p. 103. “ Bottom of rock-pools at extreme 
low water, spring tides, Shetland ” (Allman). 
attenuata, Allman, Ann. Nat. Hist. 3rd ser. vol. xiv. p. 60. “ Dredged 
from about 50 fathoms in the Shetland seas” (Allman). In 1867 I pro- 
cured a Tubularia in some quantity 5-8 miles to the east of Balta, which, 
not being able to recognize, I sent to Prof. Allman to examine. He refers 
it to the present species, and writes: ‘ It has certain distinctive features 
it is true, but nothing which I regard as sufficient to separate it from 
T. attenuata. The specimens on which I founded this species were 
male, while your specimens are female; and I believe that the difference 
in the gonosome between the two forms may be sufficiently explained 
by referring them to a difference of sex.” 
coronata, Van Ben.,= 7’. gracilis, Harvey. Haddock-ground, Out Sker- 
ries and Unst. 
larynx, Ellis & Sol. Caves at Burrafirth, spring tides, and 5-7 miles 
east of Balta, in 40-50 fathoms, on Tubularia indivisa. 
Corymorpha nutans, Forbes & Goodsir. 5-7 fathoms in Balta Sound. 
Order CALYCOPHORIDA. 
Diphyes (2? appendiculata, Eschscholtz). A beautiful Diphyes, the nectosaes of 
which were of a delicate rose-colour, occurred in profusion in the open 
sea, about 30 miles N.N.W. of Unst, in July 1867. Unfortunately, as 
I had no works with me at the time, I am unable to identify the 
species. The rapidity in its growth was most extraordinary; the cce- 
nosare of a specimen kept alive was developed nearly 3 inches in a 
single night. 
Order PHYSOPHORIDA. 
Physophora (? borealis, Sars, Bemeerkninger over norske Ccelenterater [Vi- 
denskabs Forh. i Christiania, 1860], p. 8). Found on the same occasion 
with the preceding; I much regret being unable to determine the species 
of the first member of this very interesting order that has been observed 
in our seas. On the only occasion on which I saw the Physophora, the
