The chief external differences between the male and female consist in the latter wanting the anal appendages, and having the fins, particularly the pectoral ones, proportionably smaller. In the course of several years during which the fishermen of Cape Town were engaged by me in collecting cartilaginous fishes, only a very few specimens of this species were obtained.Their want of success, however, probably arose more from the species resorting to situations little visited by fishermen during their ordinary avocations, than from the scarcity of specimens. It feeds upon mollusca, Crustacea, Sfc, and in quest of these it haunts principally the rocky, or broken parts of the coast.Specimens of this species are occasionally procured, in which the ground colour, similar to that described, is freely spotted with dusky black blotches, very various as to size.As I have not had an opportunity of ascertaining whether the males of the species of this genius are provided with sacs, similar to those which occur in several of the other genera of the Squalidce, and which sacs appear to be connected with the anal appendages, I would suggest the inquiry, as deserving the attention of those naturalists who have an opportunity of examining specimens of the European species. The sacs to which I allude, two in number, lie under the skin of the abdomen, immediately in front of the anus, are of a pyriform shape, and each, by means of a narrow duct, opens into the longitudinal groove, which exists on the inner side of each anal appendage. In none of the sacs which I examined was I able to detect any fluid beyond what was barely sufficient to lubricate their inner surfaces, and from whence it proceeded I could not discover; no glandular structure was noticed. Farther enquiries, I have no doubt, will shew them to be essential to the proper performance of the functions belonging to the appendages; and as tending to give probability to that supposition, I may merely observe that by injecting water into one of these sacs, the corresponding appendage was distended to a great size, and its apex expanded, flattened, and rendered well adapted for fixing upon, or seizing extraneous bodies. * The notes descriptive of the colours of the fish, as they appeared when it was caught, have been mislaid.
