strigis olivaceo-fuscis, plerumque radiantibus, interdum confluen- 

 tibus picta ; apice ssepius nigro ; intus albida, margiue satis lato, 

 strigis tessellato. Long. -9, lat. '74, alt. -3 poll. 

 Variat colore hie et illic aurantiaco tincto : strigis omnino tessellatis. 

 According to Darwin, this might be regarded as a cross be- 

 tween the northern forms A.pelta and A.patina, about to change 

 into the Gulf species, A. mesoleuca. The dark variety resembles 

 A. cantharus, but the very delicate crowded striae well distin- 

 guish it when not abraded. 



18. Glyphis satumalis. 



G. testa G. inaquali simili, sed minore, latiore, altiore, tenuissime 

 caucellata ; striis radiantibus plus minusve propinquis, plus mi- 

 nusve nodulosis ; fissura prope trientem longitudinis sita, minima, 

 liueari, medio lobata; intus callositate albida, truncata. Long. '38, 

 lat. -24, alt. -18 poll. 



The minute hole resembles the telescopic appearance of Saturn 

 when the rings are reduced to a line. 



Subgenus Eucosmia*. 



Testa solida, nitida, variegata, baud nacrea : apertura et anfractus 

 rotundati : conspicue umbilicata : peritrema vix continuum, baud 

 callosura. 



The shells here grouped are like small, round -mouthed, per- 

 forated Phasianella. The animal and operculum of the Cape 

 St. Lucas species are unknown. The Phasianella striulata, Maz. 

 Cat. no. 283 h { = Turbo phasianella, C. B. Ad. Pan. Sh. no. 282), 

 and even the Lunatia tenuilirata, Maz. Cat. no. 572, are perhaps 

 congeneric. 



19. Eucosmia variegata. 



E. testa parva, laevi, turbinoidea, nitente, marginibus spirse valde 

 excurvatis ; rosaceo et rufo-fusco varie maculata ; anfr. nucleosis 

 regularibus, vertice mamillato ; normalibus iv., valde tumentibus, 

 rapide augentibus, suturis impressis ; anfr. ultimo antice producto ; 

 basi rotundata ; umbilico carinato ; apertura vix a pariete inden- 

 tata; peritremate pene continuo, acuto. Long. '1, long. spir. "05, 

 lat. -07 poll., div. 70°. 



Variat interdum rugulis incrementi ornata. 



20. Eucosmia (? variegata, var.) substriaia. 

 E. testa E. variegatce simillima, sed anfr. circa basin et supra spiram 

 (nisi in anfr. nucl. Isevibus), interdum tota superficie tenuiter et 

 crebre striatis ; striis anfr. penult, circ. x. 



21. Eucosmia punctata. 



E. testa E. variegatce simili, sed multo majore, multo magis elon- 



* Th. fv, well ; Koa-fiia, adorned.
