373. CoRBULA RUGIFERA, n.sp. Pl. XV, Figs. 9 and 10. 
Corbula rugifera, A. Adams MS. in Coll. Cuming. 
Testa oblonga, antice rotundata, postice acuminata, ineequilateralis, 
inequivalvis, alba, versus umbones rosea, radiis paucis pellucidis 
seepe picta; valvee postice oblique carinate, ante carinam concentrice 
irregulariter costulate, pone carinam corrugate ; margo dorsi postica 
leviter obliqua, recta, antica magis declivis, brevior, ante umbones 
leviter concava; umbones ante medium siti, incurvati, haud contigui; 
pagina interna albida, flavescens vel fusco tincta, postice rosacea. 
Long. 18, alt. 8, diam. 5°5 mm. 
Hab.—Umkomaas (Burnup),. 
This is the only species apparently that has the posterior area behind 
the umbonal angle peculiarly obliquely wrinkled. This feature alone 
will separate it from allied forms. The few pellucid rays upon the 
central portion of the valves are much more distinct in some specimens 
than in others. 
374. Panopea Natatensts, Woodward. 
Panopea Natalensis, Woodward: Proc. Zool. Soc., 1855, p. 220. 
Panopea australis, Valenciennes: in Chenu’s Ill. Conch., pl. viii,

Lucina (Divaricella) quadrisuleata, Sowerby : Marine Shells 8, Afr., 
Appendix, p. 26 (nee D’Orbigny). 
Hab.—Natal. 
This species differs from Z. guadrisulcata not only in the characters 
pointed out by Mr. Vanatta, but also in being flatter and in the kind 
of crenulation of the margin of the valves.
