26 H. Doc, 129. 



Locality. Found at San Diego by Mr. Blake and also by Mr. Webb. 



This pretty little shell is usually more or less coated with cretaceous 

 matters, but when cleaned exhibit a beautifully lineated surface, pe- 

 culiar on account of the lines running so nearly in the ordinary direc- 

 tion of revolving stria3. The coloration, however, sometimes consists 

 of olive and white tessellations and blotches. It would accord pretty 

 well with P. perforata, Philippi, did it not lack the distinguishing 

 mark of that species, its perforation. 



BULLA (TORNATINA) INCULTA, Gould. 



Testa minuta, solidula eburnea elongato-ovalis, longitudinaliter 

 minutessime striata; spiraelevata; anfractibus quatuor tabulatis; aper- 

 tura linearis, octantes, septem lorigitudines testae adequans, antice 

 dilatata, postice rotundata; labro incurvato; columella satis arcuata,, 

 callossa uniplicata. PI. , fig. . 



Shell minute, solid, ivory white, elongated-oval, minutely striated 

 longitudinally; spire elevated, consisting of about four tabulated 

 whorls. Aperture about seven-eighths the length }f the shell, not 

 attaining the end of the outer whorl, linear, constricted at the middle 

 and somewhat dilated anteriorly, posterior angle rounded; pillar mod- 

 erately arcuate, usually presenting a well marked fold at the anterior 

 fourth and well coated with enamel. 



Length one-eighth; breadth one-twelfth of an inch. 



Locality. San Diego. 



May be best compared with B. fusiformis, A. Adams, and is also 

 very closely allied to B. obstincta, Gould. The spire varies much in 

 elevation, sometimes, indeed, being on a level with the outer whorl. 

 The form of the whorl shell is also more or less cylindrical. 



BULLA (HAMINEA) VESICULA, Gould. 



Testa parva, fragilis ovato-globosa, palide citrina, postice truncata; 

 apertura spiram superans, longitudene duplo adequans, antice et pos- 

 tice bene rotundata; columella profund arcuta, vix callosa. PL , 

 fig. . 



Shell small, fragile, ovate globose, pale greenish yellow; body of 

 the shell small, truncate at summit; outer whorl large; aperture about 

 twice the length of the body of the shell, and projecting above it, 

 broadly rounded both posteriorly and anteriorly; outer lip inflexed 

 at the middle; pillar profoundly arcuate, with a narrow delicate 

 callus.

Locality. Brought from San Diego by Mr. Blake. 



It has about the size and general appearance of B. rotounda, A. 

 Adams, but has not so large a body, and is more open anteriorly; in 

 this latter respect it is more like B. Natalensis, a much larger shell. 



CARDIUM CRUENTATUM, Gould. 



Testa parva, tenuis, transversim rotundato-ovata, rentricosa, in- 

 equilateralis, polita, straminea, ad aream dorsalem posticam rufo
