Cardita pica. Card, testd elongato-ovatd, gibbd, alba, nigro aut 

 fusco varie inquinatd; costis septemdecim sedecimve, in medio 

 a?igulatis, subtiliter squamosis ; intus alba, postice nigenimo- 

 fuscd. 

 Conch. Icon., Cardita, pi. 2. f. 8. 



Hab. Island of Guimaras, Philippines (found under stones at low 

 water) ; Cuming. 



There is a peculiarity in the shape and blotching of this shell 

 which entitles it to be distinguished as a new species. Several 

 specimens were collected by Mr. Cuming at the above-mentioned 

 island, singularly agreeing in respect to these characters. 



Cardita gubernaculum. Card, testd ovato-oblongd, depressd, 

 antice brevissimd, angustd, postice latissime rotundatd, subalatd ; 

 brunned, luteo purpureoque umbones versus tinctd ; costis plus 

 minusve squamosis, superioribus perpaucis, majoribus, inferiori- 

 bus angustis numerosis ; intus brunned, antice albicante. 



Var. j3. Testa alba, fusco vix tincta. 



Conch. Icon., Cardita, pi. 3. f. 9. 



Hab. Zanzibar. 



This is the nearest allied species to the C. semi-orbiculata ; the 

 dark variety might indeed be easily mistaken for it, were it not for 

 the scales and peculiar elongation of the ventral portion of the shell. 



Cardita marmorea. Card, testd elliptico-ovatd, postice rotun- 

 datd, antice peculiariter brevi ; lacted, nigro umbones versus ma- 

 culatd ; costis quindecim sedecimve, recto-elongatiuscule radian- 

 tibus, latescentibus ; anticis crenatis, intus eburned. 



Conch. Icon., Cardita, pi. 3. f. 12. 



Hab. New Holland. 



Cardita distorta. Card, testd elongato-ovatd, valde gibbosd, 

 peculiariter distorta, luteold ; costis duodecim aut plurimis, sub- 

 squamosis, inferioribus planiusculis. 



Conch. Icon., Cardita, pi. 4. f. 13. 



Hab. Red Sea ; Riippell. 



There are several specimens of this curious species in Mr. Cu- 

 ming's collection, all singularly distorted in the same manner. 



Cardita Senegalensis. Card, testd oblongd, elongato-ovatd, 

 fulvd, epidermide fused indutd ; costis quindecim sedecimve, squa- 

 mosis, squamis incumbentibus. 

 Conch. Icon., Cardita, pi. 4. f. 1C. 



Lejesonl Adanson. 

 Hab. Senegal. 



This shell, which I know to have been brought from Senegal by 

 M. Rang, approaches nearer to the figure and description of Le 

 jfoon of Adanson than any that has been hitherto assigned to it. 



Cardita volucris. Card, testd elongatd, postice valde gibbosd t 

 angulatd, antice brevi et coarctato-acuminatd ; viridescente albidd, 

 postice nigrd nigroque maculatd ; costis septemdecim, anticis 

 planulatis, marginem versus evanidis ; posticis angulatis, hinc 

 illinc obsolete squamosis*
