214 PROCEEDINGS OF THE CALIFORNIA 



Genus Scurria (?), Gray. 

 Scurria (?) funiculata, Cpr. (?) n. s. State Collection, No. 466rf. 



? Sc. t. parva, albida, regulariter conica, apice acuto, elevato, parura antror- 

 sum sito ; liris validis, rotundatis, interdum vix nodulosis, irregulariter, hue et 

 illuc duplo vel tripliciter dispositis ; margine a costis extus undato ; cicatrice 

 haud conspicuo. 



Long. 0-50, lat. 0-38, alt. 0.26, div. 80°. 



Hab. Monterey, 6 dredged dead, Cooper. 



So different from the most strongly marked young specimens of Sc. mitra 

 that I presume it to be distinct. The genus depends on the animal, which has 

 not yet been seen. 



Genus Puncturella, Lowe. 

 Puncturella Cooperi, Cpr. n. s. State Collection No. 1029. 



P. t. "P. galeatce," fere exacte simulante ; sed lamiDa interna solida, planata, 

 haud antice siuuata, haud suffulta. 



Long. 0-30, lat. 021, alt. 0-24, div. 70°. 



Hab. Catalina Island, not rare, 40 to 20 fms., Cooper, alive. 



Outside like P. noachina ; but with the lamina like P. cucullata, without eye- 

 holes. The latter species is extremely variable in sculpture, but never so fine 

 as this ; and the shape is less conical. 



Genus Gibbula, Leach. 

 Gibbula optabilis, Cpr. n. s. 



G. t. parva, pulcherrima, subconica ; lurida, fusco-purpureo maculata ; anfr. 

 v. subquadratis, suturis distinctis ; carinis priocipalibus in spira ii., alia interca- 

 late ; carina fortiori peripheriali, et lirulis circ. vi. basalibus, regulariter colore 

 punctatis ; lira postica subobsolete suturam attingente ; aliis minoribus inter- 

 calantibus ; interstitiis ubique tenerrime et creberrime decussatis ; basi sub- 

 tumente, ad carinam peripherialem fere rectangulato ; apertura subquadrata, 

 columella parum arcuata; umbilico magno, iufundibuliformi, angulato; liris 

 ii. intus spiraliter ascendentibus. 



Long. 0-19. long. spir. 0-10, lat. 0-19, div. 80°. 



Hab. San Pedro, Palmer, one specimen. 



Genus Calliostoma, Swainson. 

 The names Calliostoma and Ziziphinus having been published in the same 

 year, I have no hesitation in preferring the generic to the specific. 



Calliostoma supragranosum, Cpr. n. s. 

 C. t. parva ; anfr. v. tumentibus ; liris acutis cincta, quarum mediae laeves, 

 posticae granosae, basales ix. minores. 

 Hab. San Diego ; Cooper. 

 The single specimen sent differs as above from the young of the next species.
