Halj. New Zealand. 



This shell in Mr. Hauley's cabinet is referred to the 



above-named Lamarokian species, on the authority of a 



continental collector from whom it was received. 



The silk-clad Lucina. Shell somewhat squarely orbi- 

 cular, inclined obliquely on the posterior side, thin, 

 depressed, concentrically impressly striated, no lunule ; 

 semitransparent white, covered with a shining pale

This and the following species are of the same cha-

 The gibbous LucaNA. Shell globose, very gibbous,

 Tellina spliaroides, Conrad. 



Hab. ? 



This tine species may be readily distinguished by its 

 very gibbous Isocardia-like form, and broad corrugate 

 cri-ooving. 



Species 5G. (Mus. Cuming.) 

 Lucina Tellinoides. Luc. testd depresso-oi-biculari,

 The Tellina-like Lucina. Shell depressly orbicular, 

 rather obliquely inclined on the posterior side, con- 

 centrically rather irregularly and very finely impressly 

 striated, no lunule ; semitransparent white, covered 

 with a sliining yellowish-horny epidermis. 

 Ilab. Isle of Mucrte, Bay of Guayaquil (in sandy mud 

 at a depth of about eleven fathoms) ; Cuming. 

 This and the allied species represented in this plate, 

 should, doubtless, be arranged under a separate genus 

 allied to Diplodotita. 



Species 55. (Mus. Cuming.) 

 ;iNA SEBICATA. Luc. tcstd subquadrato-orbiculmi, 

 postice oblique inclinatd, teiiui, depressd, concentric!} 

 impresso-striatd, lunuld nulld ; semipellucido-albd,

 tenui, tumidd, coneentrice subirregulariter et tenuissime

I The fuiable Lucina. Shell orbicular, nearly equi- 



j lateral, thin, swollen, concentrically rather irregularly 



' and very finely striated, no lunule ; pinkish-white, 



covered with a thin shining horny epidermis. 



Hab. ? 



Belonging to the same type as the preceding species, 

 fi-om which it differs specifically in being of a more 

 rounded swoUen form and of larger size.
