 libus rarioribus et costis obtusis supra suturam 3, infra 5 sculpta, 

 subunicolori, rufo-fusca ; spira turbinata, apice obtusa ; anfr. 4£,

Allied to C. tigrinus, Sow., but of smaller size, the last whorl 



more flattened, the inner lip scarcely dilated, never covering the 



umbilicus. On the upper whorls a flammulatecl pattern is 



sometimes found, as in C. tigrinus. 



3. Tellina semilaevis.

 coccineis ; valva dextra sulcis concent ricis confertis scabra, sinis- 

 tra Icevis, nitida ; margo ventralis antice arcuatus, postice ascen- 

 dens, dorsalis antice vix declivis, convexiusculus, postice descen- 

 dens, primum concavus, dein convexus ; pars antica longior, pos- 

 tica rostrata, biangulata, angulo superiore magis obtuso ; costse 

 umbonales valvse dextrse duae subsequales, rotundatse ; flexura 

 distincta ; dens cardinalis (compressus, prominens) unus in valva 

 sinistra, duo in valva dextra ; ligamentum breve, immersum ; 

 dentes laterales nulli. 



Long. 48, alt. 24, crass. 10 mill; vertices in T 7 ? longitudinis. 



Querimba Islands, near Mossambique (Peters) ; Red Sea

 trali vix ascendente, dorsali postice subrectilinco ; flexura indis-
