ZOOLOGICAL LITEIIATUIU!:. 
W. Archer exhibited specimens of this beautiful new form to the Micro- 
scopical Club of Dublin in April 1867. Quart. Journ. Mic. Sc. vol. xv. p. 295. 
The specimens were taken near Dublin, but were not named at the time. 
Forammifera. Deiohert (/. c.), in his memoir on the contractile sub- 
stance (sarcode, protoplasm) and on the motory phenomena in the Poly- 
thalamia and some other of the lower animals, recapitulates in great detail his 
views on this subject. This memoir is illustrated by seven plates {yida 
Zool. Record, 1866, p. 646). 
Hauerina compressaj d’Orb., well known as a tertiary fossil, is mentioned 
by Brady as found in a recent state in the Hebrides (/. c. p. 69). 
Valmdina conictty d’Orb., Trochammma squamata, P. & J., and T. gordialis, 
P. & J.., are mentioned by Brady (/. c.) as new to the British fauna, having 
been found in the Hebrides. 
Lagena Jeffrey siif sp. n., Brady, 1. c. p. 70, Hebrides j L. pidchella, sp. n., 
Brady, 1. c. p. 70, Hebrides. — L. gracillima, Sequenza, L. lyellii, Sequenza, and 
L. crenata^ P. & J., are recorded by Brady (/. c. p. 70) as new to the British 
fauna; Hebrides. 
Glohigerina. Major Owen (/. o.) gives a good deal of interesting informa- 
tion as to the geogi-aphical distribution of several species of this genus and of 
PidvinuUna ; several varieties of G. bidloideSj G. injlata, G. continetiSy P. crassa, 
P. rnenardiij &c. are figured. Major Owen proposes to make Orhulina a sub- 
genus of Glohigerina. 
A series of soundings, twenty-nine in number, were made in November 
1866, by Captain Oesterreicher, of the Austrian Navy, along the southern 
part of the west coast of the Istrian peninsula. Some of these )delded large 
quantities of small and of relatively large Foraminifera, such as Polystomella 
crispa, Lam., Rotalia beccarii, Linn., Trilocidina trigomda (Lam.), &c. Pene- 
roplis planatus, F, & M., occurred very rarely in a few shallow places. Jahr- 
buch d. k.-k. geol. Gesellfechaft, Wien, Feb. 19, 1867, p. 62, and Ann, & Mag. 
Nat. Hist. vol. xix. 1867, p. 87k 
Labyrinthula. Professor Cienkowski (/. c.) describes some veiy remark- 
able organisms met with incrusting some of the lower algse found on the 
piles in the Port of Odessa. They consist of minute microscopical threads, 
which form thin colourless and intricate ramifications. Spindle-shaped 
bodies glide very slowly, in different directions, through the threads. The 
meshes are of very varied shapes and sizes, with arcuately curved outlines. 
Two sufficiently distinct species were met with, L. vitellina and L. macro-' 
cystis. The latter species was found living far higher up on the piles than 
the former species, even above water-mark. It would appear premature to 
decide at present where to locate these strange organisms. Even should they 
eventually be found not to belong to the domain of the zoologist, there needs 
no apology for alluding to them here. 
IV. GREGARINIDA. 
McIntosh describes (1. c.) a gregariniform parasite met with in Borlasia 
octoculata and P. olivacea, which may possibly be Gregarina nemertis.
