collected at Cape St. Lucas. |. 2a 
- strigis olivaceo-fuscis, plerumque radiantibus, interdum confluen- 
_tibus picta ; apice seepius nigro; intus albida, margine satis lato, 
strigis tessellato. Long. °9, lat. 74, alt. *3 poll. 
Variat colore hic et illic aurantiaco tincto : strigis omnino tessellatis. 
According to Darwin, this might be regarded as a cross be- 
tween the northern forms 4. pelta and A. patina, about to change 
into the Gulf species, A. mesoleuca. The dark variety resembles 
A. cantharus, but the very delicate crowded strie well distin- 
guish it when not abraded. 
18. Glyphis saturnalis. 
G. testa G. inequali simili, sed minore, latiore, altiore, tenuissime 
cancellata; striis radiantibus plus minusve propinquis, plus mi- 
nusve nodulosis ; fissura prope trientem longitudinis sita, minima, 
lineari, 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 Evcosmia*, 
Testa solida, nitida, variegata, haud nacrea: apertura et anfractus 
rotundati: conspicue umbilicata: peritrema vix continuum, haud 
callosum. 
The shells here grouped are like small, round-mouthed, per- 
-forated Phasianelle. The animal and operculum of the Cape 
St. Lucas species are unknown. The Phasianella striulata, Maz. 
Cat. no. 283 b (= Turbo phasianella, C. B. Ad. Pan. Sh. no. 282), 
and even the Lunatia tenuilirata, Maz. Cat. no. 572, are perhaps 
congeneric. 
19. Hucosmia variegata. 
H, testa parva, levi, turbinoidea, nitente, marginibus spire 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.) substriata. 
£. testa EL. variegate simillima, sed anfr. circa basin et supra spiram 
(nisi in anfr. nucl. laevibus), interdum tota superficie tenuiter et 
‘crebre striatis ; striis anfr. penult. cire. x. 
21. Eucosmia punctata. 
ZH, testa E. variegate simili, sed multo majore, multo magis elon- 
* Th. ed, well; xoopia, adorned,
