ON SEVEN NEW SPECIES OF MARINE MOLLTJSCA COLLECTED BY 

 DR. H. BECKER AT "THE KOWIE," SOUTH AFRICA. 



By G. B. Sowerby, F.L.S., etc. 



1. Trophon Kowieensis. PL XXII, Fig. 16. 



Testa elongata, angusta, pallicle fulva, antice breviter acuminata, 

 postice prolongata ; spira acute turrita ; anfractus 6, primus rotundatus, 

 lsevis, pellucidus, albus, sequentes convexi, biangulati, liris spiralibus 

 2-3 cingulati, longitudinaliter creberrime costati, sutura impressa 

 sejuncti ; anfractus ultimus spiram paulo brevior, leviter inflatus, liris 

 spiralibus 7, instructus, infra attenuatus, breviter rostratus ; apertura 

 ovata ; labrum vix incrassatum ; columella rectiuscula, basim versus 

 leviter recurva ; canalis latiusculus, leviter sinistrorsum obliqua. 

 Long. 6, diam. 2 mm. 



It may be doubted whether this is a true Trophon ; it evidently 

 belongs to the same group as the species described by me last year, 1 

 from the same locality, as Trophon insignia. On the other hand, it 

 approaches some of the species provisionally placed in Ocinebra, such 

 as Murex scrobiculatus, Dunker. 



2. Mitra Kowieensis. PI. XXII, Fig. 17. 



Testa ovato-f usiformis, alba ; spira breviuscula, leviter convexa ; 

 anfractus 6, convexi, spiraliter leviter sulcati, longitudinaliter costati, 

 costis 12, crassiusculis, rotundatis, aequalibus ; anfractus ultimus 

 spiram fere aequans, leviter inflatus, ad basim paulo attenuatus, 

 spiraliter nodoso costatus, haud rostratus ; apertura oblonga, 

 latiuscula ; labrum simplex ; columella quadriplicata. Long. 5, 

 diam. 2 mm. 



This little, white shell is somewhat like Mitra bathyraphe, Sby., 

 but has not the channelled suture characteristic of that species. 



3. TlJRBONILLA BATHYRAPHE. PI. XXII, Fig. 18. 



Testa acute pyramidata, alba ; spira erecta ; anfractus 9, planato- 

 convexi, primi 2 lseves, sequentes liris spiralibus 4 elatis rotundatis 

 angustiusculis cingulati, longitudinaliter acute laminati, sutura pro- 

 fuude canaliculata disjuncti; anfractus ultimus \ longitudinis testae 

 aequans, liris 6 instructus ; apertura ovata ; labrum dentatum ; 

 columella arcuata, glabra, leviter callosa. Long. 7, diam. 2 mm. 



A pure white shell, strongly latticed, with prominent spiral ridges, 

 and a remarkably channelled suture.
