The shell of this species is more attenuate than the last, and the mouth and beak longer and much narrower ; seven strong ribs proceed from base to apex in the manner of those on Pleurotoma septangularis, to which it is nearly allied, but differs, besides form, in being spirally striated : it is nearly as strong. Its colour is dusky white, with obscure rufous spiral bands. Several specimens were dredged at the same time and place with the last. VIII. Patella ? ancyloides. Nov, Sp. Forbes, Plate II. fig. 16.

Possibly a Lottia, A shell so nearly resembling an Ancy-lus, that had I not dredged it, I should have looked on it as such. The apex is more incurved than in any of our other species of smaller Patellae, and the shell much more conical. It was dredged along with the two last described species in Lamlash Bay, Arran. XIII. — Catalogue of the Species of Reptiles collected in Cuba by W. S. MacLeay, Esq. ; — with some Notes of their Habits extracted from his MS, By J. E. Gray, Esq., F.R.S. The Catalogue is a continuation of the former one of Mam-malia from the same island, published in a former Number of this work, vol. iv. p. 1. It is worthy of remark that all the species described in the former paper are different from any mentioned in the Fauna of Cuba now in course of publication by M. Sagra. Several of the reptiles contained in this list appear to have been also found by that naturalist ; but others which have been brought home by Mr. MacLeay we have reason to think have escaped his research. As the species of the genus Anolis are difficult to distinguish, and as there are several species in the British Museum which I cannot refer with any certainty to the species described by
