This species differs from the Conus interruptus in having the spire 

 narrower and much more elevated ; it is always more strongly and 

 fully stained with the dark reddish-brown, and the interior of the 

 shell exhibits no indication of any purple. 



Conus intermedius. Con. testd elongato-turbinatd, subcylindraced, 

 Icevi, columella basim versus subtiliter sulcata ; puniceo-rosed, 

 maculis grandibus fuscescentibus reticulatis, interrupts bibalteatd, 

 interstitiis plus minusve pallide reticulatis ; spird convexo-elatd, 

 spiraliter striata ; aperturd patente, fauce pallide violaced.

I have long suspected this shell to be distinct from the Conus geo- 

 graphus ; it differs constantly in form, in colour, and in the general 

 distribution of the brown reticulated painting. These differences 

 are unimportant however compared with a character which it has in 

 common with the Conus tulipa, namely that of having the lower por- 

 tion delicately grooved. The base of the Conus geographus does not 

 present the slightest indication of this grooving, nor indeed any in- 

 equality of surface beyond the ordinary strise of growth, which pass 

 in the contrary direction. I notice this character in the Conus inter- 

 medius merely to show that it cannot be a variety of the Conus geo- 

 graphus ; the grooving must not be regarded as a specific peculiarity, 

 because, as already observed, it is common to the Conus tulipa, as 

 well as to another closely allied species, the Conus obscurus. 



Conus orbitatus. Con. testd oblong o-turbinatd, tenuiculd, trans- 

 versim liratd, liris planis, interstitiis striato-pertusis ; albidd, 

 ustulato-fusco variegatd; spird acuminatd, apice elato, acuto.

I kindly thank M. Deshayes for the use of this interesting little 

 shell, which at first sight I thought to be a young specimen of the 

 Conus sulcatus. 



Conus elongatus. Con. testd elongato-turbinatd, Icevi, luteo- 

 olivaced, superne cceruleo-albd, fascid interruptd subindistinctd 

 deorsum cingulatd -, spird convexd, cceruleo-albd, subtilissime co- 

 ronatd, apice rosaceo ; basi et apertures fauce vivide violaceis.

I adopt the Rev. Mr. Stainforth's manuscript name for this elegant 

 little shell, believing that it may with great propriety be regarded as 

 a new species. 



Conus iouostoma. Con. testd subelongato-turbinatd, tenui, leviter 

 inflatd; albidd, purpureo pallidissime tinctd, luteo-fuscescente 

 sparsim et irregulariter punctatd et maculatd ; spird subtilissime 

 sulcata, apice elato, acuto ; aperturd latiusculd, fauce violaceo- 

 purpured.
