COPEPODA. 
A, Gruber describes the formation of the spermatozoids and sperma- 
tophores in the Copepods, and their transmission to the females. In some 
genera of the CalanidcSj as Heterocope., Diaptomus, Temora, Candace, and 
Ichthyophorba, there is no special receptaculum seminis, the spermato- 
zoids, cemented together by glutinous matter, are transferred directly to 
the vulva. In all Cyclopidce and Harpactidce examined by the author, 
there is, on the contrary, a single distinct receptaculum seminis, in the 
median line of the belly ; the same also is found in some genera of 
Calanidce, as Pleuromma, Leuchartia, and P achy soma. Other Calanidce, 
as Cetochilus, Calanus, Calanella, and Dias, have two symmetrical recep- 
tacula, one on each side ; generally each receptaculum is provided with a 
special external orifice (porus) ; the spermatophores are attached near to 
this orifice, and their contents enter by this orifice into the receptaculum 
and come from thence to the eggs. The matter for forming the ovisacs 
is never furnished by those receptacula, but only by the oviducts them- 
selves. Z. wiss. Zool. xxxii. pp. 407-442, pis. xxiv.-xxvii.
