This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1868 Excerpt: ...Cypris, nor even in Candona. The two or three specimens on which the species was originally founded are all that have as yet been observed. It may be noted that specimens of Cypris gibba sometimes assume a tuberculated or spinous surface; but never, so far as I know, to such an extent as in the present species. Genus 3. Cytheridea, Bosquet. Shell, as seen from the side, subtriangular or triangularly ovate, highest at the anterior third; thick and compact in structure. Surface more or less pitted, sometimes smooth and papillose, or concentrically rugose. Hinge-margin of the right valve bearing a series of small tubercles or crenulations, which are received into corresponding depressions of the opposite (left) valve; these tubercles are mostly disposed in two terminal groups, the intervening portion of the valve-margin being plain or marked by minute tubercles on the left, and corresponding fossae on the right valve. Lucid spots about four, in a transverse row, near the centre of the valve, and two detached spots (which sometimes coalesce) in front of the main group. Upper antennae very robust, mostly five-jointed and bearing strong spines; the last joint narrow and elongated; lower antennae fourjointed; urticating setae long and slender, biarticulate. Mandibles large and numerously toothed; palp three-jointed, and bearing a distinct branchial appendage. The right foot of the first and second pairs in the male different from the rest, that of the first pair very strong and prehensile; of the second very feeble, the apical portion rudimentary and destitute of a terminal claw. Eyes distinct. I am unable to find any good distinctive characters to separate the genus Cyprideis (Jones) from Cytheridea. G. O. Sars restricts the latter genus (apparently) to certain v...
