mr. lsevis. Equally distributed with the typical form, and not separated from 
it by the authors quoted above. 
Tectura testudinalis, Muller. 
On stones at and below low water mark. Newcastle and Bloody Bridge 
Thompson [sub Lottia testudinalis). Frequent on both sides of Belf ast Lough 
— Hyndman; and dead specimens were dredged in Strangford Lough by 
Dickie, and Mr. S. A. Stewart {Acmcea testudinalis). This shell was named 
by Sowerby Tatella Clealandi in honour of Mr. J . Bose Clealand, of Bathgael 
House, who procured the first British examples at Bangor, Co. Down ; but 
as a species it proved to have been previously described and named by Muller, 
from Danish specimens. On stones near the Twin Islands, Belfast Harbour, 
of large size — Mr. Swanston. 
Tectura virginea, Muller. 
“ Obtained on the shore of Belfast Bay by Mrs. M‘Gee, and found by Mr 
Hyndman adhering to oysters in Belfast Market in 1831 ’’-Thompson {sub 
Lottia virginea). Hyndman took it very frequently, living at the entrance 
to Belfast Lough, and off Larne, in from 10 to 25 fathoms ; and rom 
Dickie’s dredgings it would appear to live in abundance in Strangford Loug , 
in 4 to 25 fathoms {sub Acmcea virginea). Dead shells frequent on t e 
Turbot Bank. 
Tectura fulva, Muller. 
Turbot Bank, rare, dead; determined by Dr. Dickie— Hyndman, 
Beport {sub Filidium fulvum).

Propilidiuzn ancycloides, Forbes. 
“ Obtained by Mr. Hyndman many years ago on oysters from Strangford 
Lough”— Thompson {sub Fatella ancycloides). In a dead state it is rather 
common on the Turbot Bank. The only locality on our shores where it has 
been certainly taken alive would appear to be the deep water near the Maiden 
Bocks, where Hyndman procured living specimens several times, in between 
70 and 100 fathoms of water! Jeffreys says “on the Antrim Coast m 18-1 
fathoms (Hyndman and others),” which looks as if some other observer had 
taken it at a less depth. 
Puncturella OToacliina, Linne. 
“ Mouth of Belfast Bay, 27 fathoms, one dead specimen dredged by Mr. 
Hyndman ’’—Thompson ; his only Irish note of the species. Hyndman 
subsequently obtained it on several occasions on the Turbot Bank (the same 
locality), always dead. Jeffreys says of it-“ Co. Antrim (Hyndman, 
Waller, and J.G.J.). The specimens, however, from the last-mentioned 
locality are probably relics of the glacial epoch, and not recent.” It is a 
species essentially of northern origin, whose most southern station is bear- 
borough in Yorkshire, while northward it ranges as far as Spitzbergen and 
North Greenland.
