Blue Lumpfish at Penzance.—The blue lumpfish (Cyclopterus lumpus, 
female) occurred, in two specimens, here last night. The peculiarity worth 
noting is that these fish were—as was also the last of the same sort which 
I had about three weeks since—taken in mackerel drift-nets, fishing at 
surface in deep water.—Thomas Cornish ; Penzance, April 27, 1876. 
Torpedo near Penzance.—I have received from a trawler a specimen of 
the electric ray (Torpedo). The trawler from whom I had it refused to sell 
it with the liver in it, preferring to keep that part himself as a specific for 
rheumatism.—Id. ; May 18, 1876. 
Large Halibut.—Messrs. Parker Bros., fish-market, have exhibited this 
week the largest halibut ever seen in the Eastern Counties, weighing 
upwards of three hundred pounds, and measuring over seven feet in 
length.—‘ Norfolk Chronicle,’ April 29, 1876. 
Hatching Eggs of Limnwus pereger.—April 29, 1876. I noticed many 
groups of eggs of Limnzus pereger deposited in various parts of a small 
aquarium (one foot diameter and fourteen inches deep), some on the glass, 
others on leaves of Valisneria spiralis, each group consisting of from sixty 
to one hundred eggs, each egg forming a little sphere, about one-thirty- 
secondth part of an inch in diameter, with the embryo on one side near the 
circumference. The only movement observed in the embryo was a slow 
rotation from right to left, or in the direction of the earth’s diurnal rotation 
upon ifs axis. 
May 3. The movements of the little mollusks within the eggs were 
various and continuous—some revolving, some alternating. The two black 
eyes are very distinct under a microscope-power of about 100-linear ; pul- 
sations of the heart very distinct and regularly performed in each second 
of time. 
May 6. Shells of the mollusks and the animals appear more granular; 
pulsations still seen through their shells. Mantle round margin of mouth 
of shell distinct; horns enlarging, showing granular substance in the inner 
base at centre; animal frequently moving and turning its shell, as the 
adult creatures do, apparently holding on by its foot to the circumference 
of the egg-shell. 
May 8. The spiral form of shell is distinctly seen to-day ; the movements 
of the mouth are obvious. The animal gradually enlarges and encroaches 
upon the inner area of its egg. 
May 10. The little mollusks are hatched and are leaving their egg-shells 
and creeping upon the sides of the aquarium: their little mouths are con- 
tinually in action, lapping the young Conferve from the glass reservoir : they 
have formed an additional calcareous layer at the mouth of their shells. 
May 11. The young mollusks have all left the eggs, and some have
