Part III — Eighth Annual Report 
i found in very shallow brachish-water barely within the reach of the 
c tide, and occasionally crawlimg on the moist weed beyond. It is a rare 
1 [or local] species, but generally plentiful where it does occur.' I obtained 
one specimen of this species in the vicinity of Skeirvuie — a small island near 
the head of East Loch Tarbert (Loch Fyne) — where Zostera marina grows 
in considerable abundance ; the specimen was kept alive for some time, 
and carefully examined by myself and others, so that though the condi- 
tions of the locality mentioned are different from those of the habitat 
which this species is said to be restricted to as stated above, there was no 
doubt as to the correct identification of the specimen. 
Note. — In the course of our examination of the stomachs of fishes, taken 
in the Firth of Forth by the 1 Garland's ' trawl-net, the Annelids Priapulus 
caudatus and Echiurus oxyurus, and the Tunicate Pelonaia corrugata 
have been occasionally observed, and in some instances so little injured as 
to indicate that they had been quite recently captured by the fish. It is 
in the stomach of the haddock and cod that these organisms are usually 
observed. Priapulus and Pelonaia have been recorded from the Forth j 
but so far as I know, Echiurus has not been hitherto observed in the 
Estuary. In St Andrews Bay, however, it is occasionally met with. 
Macropsis slabberi, which, as a British species, was considered to be con- 
fined to the upper part of the Firth of Forth, has been taken by me 
during the last year in the vicinity of the Bass, in St Andrews Bay, and 
and in the Estuary of the Tay opposite Tayport ; this would indicate that 
its distribution is not so restricted as was supposed, or that it is spread- 
ing gradually to other parts of our coast. I have also obtained the 
somewhat rare Isocardia cor and Palmipes membranacea (placenta) in the 
Moray Firth. Of the first, two large specimens — one living and one dead 
— were brought up by the trawl of the ' Southesk ' last year during the time 
I was on board; a specimen of the other was brought up by the ' Southesk's ' 
trawl on one or two occasions while I was on board in the early part of 
this year (1890). 
CORRIGENDA. 
In my paper 1 Some Additions to the Fauna of the Firth of Forth,' in 
last year's Report, the Amphipods referred by me to Gammarus edwardsi, 
Spence Bate (p. 321), I am now satisfied do not belong to that species, 
but are a form of G. locusta, L. 
Note on Cymbasoma rigidum (Thompson), Scott, ' Some Additions to the 
' Fauna of the Firth of Forth,' Seventh Annual Report, pt. iii. p. 316 
(1889). 
In a paper by G. C. Bourne, M.A., F.L.S., Director of the Plymouth 
Laboratory of the Marine Biological Association, on the genus Monstrilla, 
Dana, in the Quarterly Journal of Microscopical Science^ this genus is 
fully and carefully described ; short descriptions are also added of various 
species belonging to it which have been more or less satisfactorily 
determined. In this paper Mr Bourne identifies Cymbasoma, Thompson, 
with Monstrilla, Dana, and refers the form recorded by me for the Firth 
of Forth in the Seventh Annual Report as Cymbasoma rigidum to Mon- 
strilla helgolandica, Claus (of which there is no previous record for 
t Vol xxx. pt. iv. pp. 565-578, pi. xxxvii. (February 1890).
