tres pallide straminei, apicales minute crenulati, subhyalini, 
ceteris spiraliter fortiter costatis; anfractu penultimo, simul ac

flab. Persian Gulf; Gulf of Oman, Maskat, 15 fathoms ; 
also at lat. 24° 58’ N., long. 56° 54’ H., 156 fathoms. 
An Euchelus of somewhat familiar aspect, but not precisely 
comparable with any species either in our National Collection 
or mentioned in existing monographs. 
Solariella zacalles*, sp.n. (Pl. XX. fig. 12.) 
S. testa depresso-conica, profunde et late umbilicata, pernitida, levi, 
solida, lete rufo-brunnea, flammis fulgetrinis maculisque spiralibus 
hic illic depicta; anfractibus 6, quorum apicales 13 crystallini, 
leeves, ceteris ventricosulis, supra, juxta suturas, regulariter spira- 
liter gemmatis, dein concentrice tenuiliratis, interstitiis perlevibus, 
ultimo infra peripheriam nitido levissimo, intus umbilicum 
pulchre multilirato, liris arcte gemmato-crenulatis, circa umbili- 
cum ipsum radiatim breviter multisulculoso ; apertura obliqua, 
subrotunda, intus margaritacea, labro tenui, columella simplici,

Alt. 4, diam. 9 mm. 
Hab. Persian Gulf; Gulf of Oman, Maskat, 10-15 fathoms; 
also in lat. 24° 55’ N., long. 57° 59’ E., 37 fathoms, sand and 
mud, and lat. 24° 58’ N., long. 56° 54’ E., 156 fathoms. 
We at first considered this species (and so inserted it in 
our Catalogue +) as identical with JLinolia gilvosplendens, 
Melv., from the Philippines{; but, though extremely 
similar, there exist some very salient points of distinction. 
The latter is far more conical and the body-whorl obscurely 
bicarinate at the periphery, the umbilical sculpture in both 
being identical, this sculpture being, in fact, the chief point 
of difference between the species under discussion and 
* Caxa\Ans, extremely beautiful.
