still of considerable size, and apparently without an oil-globule, bnt 
the sac was injured. The somewhat elongate body is surrounded 
by a deep marginal fin (it is shrivelled in the sketch) which is minutely 
speckled with vesicles, as in the brill and turbot, though in this 
eximple they appeared finer than in either — a condition, however, that 
might have been due to the mode of preparation. The great elongation 
of the body in proportion to the size of the yolk-sac is diagnostic in con- 
trast with most larva?, and the depth of the marginal fin in the caudal 
region is also noteworthy. A distinct pre-anal portion of the marginal 
fin occurs between the yolk-sac and the anus, which is at the ventral edge. 
An opaque region about midway between the lens and the posterior 
border of the yolk probably indicates the otocyst. A few black chromato- 
phores occur on the head, and are continued along the side to the ventral 
border of the notochord. They form a somewhat interrupted series along 
the ventral muscle-plates to the tail, a few likewise occurring dorsally in 
the latter region. 
Station II. — Surface, 15th April 1892. Small collection. A few eggs of 
haddock, embryo from J round to stage with tail touching head ; a very few 
eggs of cod , a few eggs of dab and flounder, embryos | to fully f round 
yolk ; six eggs of long rough dab, embryos nearly ready to hatch ; 1 egg 
of plaice, embryo J round yolk. 
Station II. — Bottom, 15th April 1892. A larger collection than 
foregoing. Considerable number of eggs of haddock, embryos J round 
yolk to tail touching head, and pigmented ; a few eggs of cod ; consider- 
able number of eggs of dab and flounder, embryos from J to § round 
yolk ; 1 egg of plaice, embryo \ round yolk. Post-larval plaice 8 mm., 
eyes symmetrical, with narrow, elongate body ; one or two young 
clupeoids, 7 mm. ; larval sand-eels, 5 mm. ; young rockling, 4 mm. ; 
post-larval armed bullheads, 5*5 to 6*2 mm. ; Montagu's suckers, 3*5 to 
6 mm. 
Station III. — Surface, 15th April 1892. — Moderate collection. Con- 
siderable number of eggs of haddock, embryo from \ to f round yolk ; a 
few eggs of cod in same stages of development ; upwards of 20 eggs of 
long-rough dab, with tail not yet free from yolk, and others almost ready 
to hatch ; considerable number of dab, with a few of flounder, at stages 
varying from embryo \ round to complete environment of yolk ; about 
the same number of rocklings' eggs (two sizes), from the stage with embryo 
just outlined to f round yolk. 
Station III.— Bottom, 15th April 1892. Moderate collection — fewer 
than foregoing. Considerable number of eggs of haddock, embryos 
pigmented in most, and from § to |- round yolk ; a few eggs of cod 
at similar stages ; a few eggs of rockling, embryos -| to f round 
yolk, and in some tail almost touching head ; 2 eggs of long-rough dab, 
in one only the tail of embryo is just free from yolk, considerable 
number of eggs of dab, with a few of flounder, embryos from \ to f round 
yolk and coloured. Young sand-eels 5 to 10 '5 mm. ; young rocklings, 4 
mm.; young Cotti, 5 '2 mm. These young Cotti, when fresh, have prominent 
pigment-touches (chromatophores) on the head and dorsum after the 
earlier stages. A pale green tint occurs on head and upper region of the 
abdomen, while a prominent bar of black passes obliquely across abdomen 
from above downward and backward. The food usually renders the 
abdomen pinkish behind the black bar. 
Station IV. — Surface, 15th April 1892. Considerable collection. 
180 eggs of haddock, with a few of cod intermingled (about 50), embryos 
from J to f round yolk and coloured; 45 rocklings, embryo § round 
yolk ; 1 egg of plaice, embryo § round yolk ; 3 of long-rough dab, from
