Hub. Philippine Islands, Australia, New Guinea, &c. 



An exceedingly variable species, both in the painting 

 and in the number and proximity of the ribs. 



Species 5S. (Mus. Cuming.) 



Mitra costellaris. Mitr. testa fusiform!, spin! acu- 

 minato-turritd ; anfractibus superne plano-angulatis ,

Hab. Island of Masbate, Philippines (found on mud-banks 

 and under stones at low water) ; Cuming. 

 The author of the ' Iconographie des Coquilles vi- 



vantes' observes, in speaking of the Mitra costellaris. 



" elle a ete nominee par Swainson Mitra crassa." By 



referring to our figure of that species (Plate II. fig. 7), 

 which is represented with even more finished accuracy 

 by Mr. Swainson in the Zoological Illustrations, the 

 reader will be enabled to form a tolerably just estimate 

 of M. Kiener's iconographical acumen. 



Species 59. (Mus. Cuming.) 



Mitra chaltbeia. Mitr. testa elongato-ovatd, basim 

 versus sulcata ; anfractibus convexis, Isvigatis, juxta 

 suturas rud'e svbtilissimi crenulalis ; cinereo-ceerules- 

 cente alboque longitudinaliter strigatd, transversim 

 indistincte fasciatd, lineis ruhido-fuscis equidistan- 

 tibus undique cingulatd ; columella rufo-aurantid, 

 quadriplicatd. 



The steel Mitre. Shell elongately ovate, grooved 

 towards the base ; whorls convex, smooth, rudely 

 very finely crenulated next the sutures ; longitudi- 

 nally streaked with white and ashy blue, trans- 

 versely indistinctly banded, encircled throughout 

 with equidistant reddish brown lines ; columella 

 reddish orange, four-plaited.

A new and very characteristic species, at present 



unique in the collection of H. Cuming, Esq. 



Species CO. (Mus. Dennison.) 

 Mitra intermedia. Mitr. testa elongato-fusiformi, 

 ut cinque attenuatd, spird acuta ; anfractibus superne 

 angulatis, transversim impresso-striatis, longitudina- 

 liter costatis, costis ad unguium leviter tuberculatis ; 

 cinereo-fuscii alboque irreijulariter zonatd ; columella 

 quadriplicatd. 

 The intermediate Mitre. Shell elongately fusiform, 

 attenuated at both ends, spire sharp ; whorls angu- 

 lated at the upper part, transversely impressly stri- 

 ated, longitudinally ribbed, ribs slightly tuberculated 

 on the angle ; irregularly zoned with ashy brown 

 and white ; columella four-plaited. 

 Kiexer, Iconographie Coq. viv., p. 73. pi. 22. f. 70. 

 Hab. Molluccas. 



This is an excellent species of M. Kiener's, fully di- 

 stinguished from the Mitra corrugata by its long atte- 

 nuated extremities.
