Station 3. 
Okoanisms from 
THE PbiVMIT. 
Organisms FROM 
Hu'rface-Nets. 
Ptkropoda (Pclseneer, Zool. pt. 65). — The following species of Pteropoda were 
observed in the deposit from this Station : — 
Limarina inflaia (d’Orbigny). 
„ lemeuri (d’Orbigny). 
n hid i monies (d’Orbigny). 
Clio ( Sli/liola ) subula (Quoy and Gaimard). 
Clio pyramidata, Linne. 
Cavolinia quadridentata (Lesueur). 
„ inflzxa (Lesueur). 
Surface Organisms. — The following are recorded as having been obtained in the sur- 
face tow-nets on this date : — 
Annelida (MTntosh, Zool. pt. 34). 
Halodora reynaudii, Andouin and M. -Edwards (?). 
Amphipoda (Stebbing, Zool. pt. 67) 
Phronimella elongata, Clans. 
In addition, the following are mentioned in the note-books: — Collosphuera and 
A anthometra in enormous abundance on the very surface; small Medusae, Agalma (with- 
out air-bladder), Diphyes, Physalia, Velella; many Copepods, Thaumops pellucida 
I" — Qystisoma spinosuni], large larva of Decapod, Ianthina , Jr terotrachea, Hyolsea 
[ = Cavolinia], Styliola, Octopus', Oikopleura. 
Wdlemoes-Suhm writes: “In the morning another specimen of Thaumops pellucida 
was captured by the tow-net. It does not show the genital papilla nor the enlarged claw 
of the fifth pair of legs ; it seems to be a male, but is very much spoiled. The trawl 
brought up a Phronimella elongata .” 
Moseley writes : “1 went out with Murray in a boat to search for surface animals. 
The sun was shining brightly, yet 1 caught three Pteropods swimming in the most lively 
i., -r on the very surface, so high as to break the water around them, and thus become 
conspicuous. Radiolarians ( Collosphssra , &c.), abounded in an astonishing manner, the 
surface being in places quite full of them, and a single scoop of the net bringing up 
:.h:rty or fort v. Sometimes they were aggregated into circular patches containing a dozen 
or moi , and at others attached to one another in strings of four or five; the majority 
w* re free. Large Velella, Physalia , and Ianthina were abundant. 1 examined the 
c flouring matter of Ianthina with the spectroscope, and found that it gave a different 
,q..Tt. nnn in acid and alkaline solutions. The flics first began to be troublesome to-day 
and -uddenly swarmed everywhere; they even accompanied Murray and me in our boat 
excursion in such numbers as to be a pest.”
