p. 26 […] Between the two anterior antennæ is a rounded projection analogous to that which in the neighbouring genera contains the inferior eye; in Labidocera, however, the eye itself is absent, at least Mr. Darwin, who examined the mouth when they were fresh, did not observe it, and had it been coloured like the other two he could not have overlooked it; and besides, though I could easily dissect out the lenses of the superior eyes, I could not find one here*.
*The colouring matter of the eyes of Entomostracans must differ chemically from that of the Zoeæ, Gammari, &c., for in Mr. Darwin's specimens (which have been in spirits of wine nearly twenty years) the colour in the former was entirely destroyed, while that of the latter was unaltered.
p. 28 […] Mr. Darwin and Dr. Baird* both regard this organ, on account of its structure and position, as the penis, in support of which it may be remarked, that Mr. Darwin observed that this pair of legs was frequently moved and retained irritability longer than any other part of the body, which appears to indicate them as the seat of some important function, which can hardly be any other than that we have assigned to them, more especially as the female organs of generation in other animals are most retentive of irritability. The penis in all Cirrhipeds is also ringed. […]
The anus is, I believe, situated between the lamellae, as I have traced the intestine thus far, and Mr. Darwin noticed its peristaltic motion in the abdomen.
* Both of whom have very kindly given me the benefit of their advice in drawing up this paper.
p. 29. Labidocera Darwinii.
There being as yet only one species in this family no specific description need be given.
Colour blue-green, sometimes with brown spots, 1/10 inch in length.
Hab. Atlantic Ocean, lat. 38° south, in the open sea off the coast of Patagonia.
I received the specimens from Mr. Darwin, to whom I am indebted for great kindness and advice, and who has kindly permitted me to call it after him.
