Caligus. The ovaries lie in the fore-part of the body, often even before 
the stomach ; the eggs come out first into the inner, and then into the 
outer oviducts. The latter have a peculiar construction, which necessi- 
tates a gradual progression of the egg. It has, namely, transverse seg- 
ments at regular distances, which must be broken through by the ripest 
egg, before it can force itself into the next empty cell. The larvae are 
like those of Cyclops and Lemma.

A NOTICE, by Hinds, is to be found in the Ann. Nat. Hist. ix. p. 256, 
that he met with, at sea, in north latitude 36° 9', west longitude 164°, 
Anatifa grouped together in bunches, without any marks of attachment 
to foreign substances. The water was likewise full of minute animals of 
the most lively motions. The Anatifa was present in astonishing num- 
bers, and 332 English miles were travelled amongst them. 
A notice of the presence of small fossil Entomostraca in Sussex, 
in limestone, has been given by John Philipps, in the Proceedings of 
the British Association, 1841, p. 64. They are small Cyprides, which 
are found in the inferior strata of limestone. Isotelus megistos, Locke 
(Sillim. Amer. Journ. xlii. p. 366, t. 3), is a large new Trilobite. It 
differs from T. gigas, by a bristle-formed process of the posterior corner 
of the shield.
