9054 ~ Insects. 
They are the horny portion of the eye of the cuttle-fish, which are preserved in the 
cemetery near Arica in Peru; and were described from specimens brought from the 
same situation by Mr. Hennah, in my ‘ Specilegia Zoologica.’ The crystaline lens of 
the human eye are of quite a different shape: 'they are more like the globular crystaline 
lens of the fish. But there can be no doubt of their being the crystaline lens of the 
eyes of the Loligo, if any one will take the trouble to compare them with the crystaline 
lens in the eyes of the recent specimens of that family. See the figures of the eyes of 
the cuttle-fish, after Cuvier, in Jones’s ‘General Outline of the Animal Kingdom, 
fig. 275, at p.590. These eyes were worn as ornaments by the Peruvians, and Mr. 
Stutchbury informs me that the natives of the Sandwich Islands sold them to the 
Russians as pearls.—J. E. Gray ; British Museum. 
Addendum to Mr. Hellins’ Paper (Zool. 8985).—The date of my paper in the last 
number of the ‘ Zoologist’ should have been February 20th, the only portion of it 
dating March 7th being the postseript to the note on Cidaria russata and C. im- 
manata, from line 7 to line 17, page 8989. The larve of C. russata, mentioned in 
my note, are now spinning, having attained a length of 13 inch; but within the last 
week I have captured some just } inch in length, which will not be full fed for two or 
three weeks. Meanwhile the largest larva of C. immanata which I have is barely 
4 inch long, and some of the eggs, which are evidently not dried up, remain yet 
unhatched.—J. Hellins ; April 11, 1864. 
Larva of Sphinx Ligustri and Liparis auriflua,—I can most fully corroborate the 
remarks of my friend Mr. Gascoyne (Zool. 8968), in contradiction of the theory 
broached by another of your correspondents (Zvol. 8906), that the larva of Sphinx 
Ligustri, when young, descends to the ground during the day for the purpose of con- 
cealment. I have taken numbers of the larve, both in the newly-hatched and every 
succeeding stage, and I have bad as many more from the egg. I always found them 
in the natural state high up on the twigs and branches (generally when small on the 
under side of a leaf), and in confinement I never observed them descend. With 
regard to your correspondent’s remarks (Zool. 8969) on the hybernation of Liparis 
aurifiua, and his astonishment thereat, I am as much astonished at his astonishment. 
The larva of L. auriflua always hatches in the autumn and hybernates, and so does 
L. chrysorrhea.— H. Harpur Crewe; The Rectory, Drayton-Beauchamp, Tring, 
March 12, 1864. 
The name ** Puss Moth” and English Names in general.—The aspect of Dicranura 
vinula, in that stage of its growth referred to by Mr. Beauchamp (Zool. 8971), may 
certainly have given rise to its name of “ puss” moth. It does not, however, appear to 
me to present at that time the strongest resemblance to the feline race. Strange to 
say, it resembles those individuals at two other periods of its existence. The young 
larva, up to the time of its second ecdysis, is exactly like a cat in miniature, when it 
is in a state of repose; and then the moth, when viewed from beneath, as when it is 
at rest upon the lid of a gauze-covered box, reminds one strongly of the head of a 
white cat. With regard to English names, the question has several times been put to 
me, “Is not a reformed English nomenclature possible?” I fear not. In attempting 
to carry out such a revision, it would be found impossible to determine, in many cases, 
which name really was the oldest applied to the insect. Besides, many would argue, 
that if we attempted to form such a vernacular nomenclature, the older name ought to
