PLATE XXV. 



CoNus BouGEi, n.sp. PI. XXV, Figs. 1, 2. 



Testa subcylindraceo-turbinata, coronata, postice truncata, antice 

 attenuata, rufo-fusca, maculis albiclis diversiformibus ornata ; spira 

 brevissima, obtusa; anfractus vix concavi, spiraliter leviter striati, 

 nodose angulati, sutura irregulariter impressa discreti ; ultimus 

 levissime convexus, liris distantibus vix conspicuis cingulatus, nodulis 

 pallidis rotundatis circiter 14 ad angulum armatus, basim versus 

 attenuatus, conspicue rotunde liratus ; apertura postice angusta, antice 

 paulo latior. Long. 21, diam. 11 mm. 



Sah. — Monac Island, New Caledonia (Bouge). 



An interesting little Cone, somewhat remarkable in character. The 

 spire is very short, and the rounded nodules at the angle are rendered 

 more conspicuous by their light colour ; the body-whorl is girdled by 

 very slightly raised, narrow, rather distant ridges ; upon a reddish- 

 brown ground, the surface is sprinkled with whitish flake-like spots, 

 which are larger, elongated, and tortuous, somewhat like hieroglyphics, 

 forming a zone below the middle of the whorl. 



A second specimen, which I call var. [i (Fig- 2), is darker in colour, 

 and has very few spots, and two or three longitudinal whitish flames 

 bordered with light yellowish brown, and the infra-median zone is 

 only indicated by a few quaint hieroglyphics. 



These two are the only specimens I have seen of the species, with 

 the exception of a very small imperfect one resembling the type. 

 I have pleasure in naming the species in honour of Monsieur Bouge, 

 who collected the specimens in the Island of Monac, New Caledonia. 

 Cythaea. stkiatissima, n.sp. PI. XXV, Fig. 3. 



Testa ovato-conoidalis, antice attenuata, postice acuminata, pallide 

 fulva vel straminea, longitudinaliter tenuiter plicata, spiraliter den- 

 sissime striata ; spira acute couica, elatiuscula ; anfractus 7^, primi 

 (2) Iseves, rotundati, caeteri obtuse angulati, supra angulum cou- 

 caviusculi, sutura angustissima discreti ; ultimus f totius longitudinis 

 testae aequans, infra angulum convexiusculus, varice crassa marginatus ; 

 apertura oblonga, mediocriter lata, utrinque leviter angustior; labrum 

 acutum, postice late sinuatum, intus denticulatum ; columella oblique 

 rectiuscula, plicis minutis numerosis instructa. Long. 9, diam. 4-5 mm. 



Hai. — New Caledonia (Bouge). 



A typical Cythara, of a very pale fulvous colour; it is very finely 

 and closely striated ; the longitudinal plicae are narrow, moderately 

 prominent, and number about 20 on the body- whorl.
