Show 1882.] PROF. F. J. BELL ON NEW SPECIES OF ASTEROIDEA. 121 uated at the base ; very closely aud beautifully inlaid with triangular scale-like markings upon a dark-brown ground, disposed in three broad bands ; the colour in the narrow spaces between the bands is lighter brown, with the markings tending to zigzag streaks ; the markings of the spire are waved streaks crossing the whorls. Length 51, width 23 millim. Mr. Melvill had named this shell in manuscript Conus euelrios; and I admit that it is quite as worthy to be considered a species as C. canonicus (Brug.), C. vicarius (Lamk.), C. verriculum (Reeve), C. archiepiscopus (Brug.), C. tigrinus (Sowerby), C. corbula scriptus (Sowerby), all of which, however, I consider varieties of Conus textile (Linnaeus). It is the opinion of some that, having got thus far, other species, such as C. abbas (Brug.), C. panniculus (Lk.), G. legatus (Lk.), &c, should be included ; but having had exceptional opportunities, from time to time, of examining large numbers of specimens of all the varieties, I continue to regard these last as species.

JEFFREY B E L L , M.A., F.Z.S. [Eeceived January 10, 1882.] (Plate VI.) Although naturalists are agreed that it is most convenient to publish descriptions of new species in connexion with a systematic review of the groups to which they severally belong, I venture on this occasion to depart from the custom, as a knowledge of these new species may be agreeable to those who are interested in the order, while the revisions can only appear slowly, and at perhaps great intervals of time. CALVASTERIAS ANTIPODUM, n. sp. (Plate VI. fig. 1.) The credit of recognizing the generic affinities of this species must be <riven to M . Perrier; for there is attached to the bottle containing it a label bearing, in his handwriting, " Calvasterias, sp." It formed part of the collection made during the voyage of the ' Erebus' and 'Terror.' R = 61; r = 19. Arms five, greatest breadth of arm 17*5 millim.
