uated at the base ; very closely aud beautifully inlaid with minute white 

 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 euetrios ; 

 and I admit that it is quite as worthy to be considered a species as 

 O. canonicus (Brug.), C. vicarius (Lamk.), G. verriculum (Reeve), 

 C. archiepiscoptis (Brug.), C. tigrinus (Sowerby), C. corbida and 

 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.), C. 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.

(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 given to M. Perrier; for there is attached to the bottle con- 

 taining it a label bearing, in his handvpriting, " Calvasterias, sp." 

 It formed part of the collection made during the voyage of the 

 ' Erebus' and 'Terror.'
