DESCRIPTIONS OF NEW SPECIES OF LAND SHELLS FROM PERU 

 AND COLOMBIA AND TWO NEW SPECIES OF CURVELLA 

 FROM THE PHILIPPINE ISLANDS. 



By S. I. Da Costa. 



Read&th April, 1906. 

 PLATE XI. 



GONIOSTOMUS SUBHYBKIDUS, n.Sp. PL XI, Fig. 1. 



Testa elongato-oblouga, fusiformis, anguste umbilicata, laevigata, 

 alba, nigro-f usco llammata, punctis opaco-albis, irregularibus aspersa ; 

 spira acuminata ; anfract. 6^7, convexiusculi, ultiiuus ad suturam 

 margiuatus, spira paulo brevior, basi attenuatus, obtuse compresso- 

 carinatus ; columella recta, reflexa ; apertura oblonga, basi angulata et 

 canaliculata ; labrum subincrassatum, breviter expansum, rubrum. 

 Long. 50, diam. 19 mm.; apertura 22 mm. longa, 9 lata. 



Hub. — Pozuzo, Eastern Peru, 800 metres. 



Of this fine shell only one specimen has been received. Its general 

 form resembles G. hyhridm, Gould, from Brazil ; it is, however, much 

 more ventricose, has an additional whorl, is ornamented with blackish 

 flames on a white ground, instead of yellow on a dark purple ground, 

 but its most distinctive feature is that it is quite smooth, whereas both 

 G. hylridus and G. goniostoma are sculptured with close and unequal 

 spiral granules. 



Drym^us spadiceus, n.sp. PI. XI, Figs. 2, 3. 



Testa pyramidali-ovata, umbilicata, tenuiuscula, laevigata, nitida, 

 oblique obsolete striata, albida, strigis spadiceis longitudinalibus 

 flexuosis picta, supra anfract. ultimum fasciisque 2 castaueo- 

 nigricantibus (altera mediana et altera basali), albo-punctatis ornata ; 

 spira elongata, ad apicem obtusula, purpurea ; anfract. 6, leviter 

 convexi, ultimus f longitudinis aequans ; apertura ampla, valde obliqua, 

 oblongo-ovalis, intus violacea ; perist. album, undique dilatatum, 

 margine dextro valde expanso, columellari dilatato et reflexo. Long. 

 39, diam. 19 mm. ; apertura cum perist. 21 mm. longa, 16 lata. 



Hah. — Bogota. 



This beautiful shell, described from an unique specimen, bears some 

 resemblance in its elaborate painting to D. Jlexuosus, Pfr., but differs 

 considerably in form, the last whorl being much larger and more 

 diagonally produced, and, in consequence, the aperture becomes more 

 oblique and larger ; also the whorls of the spire are flatter than in 

 B. flexuosus, and the body-whorl lacks the dark crescent behind the 

 umbilicus as in that species.
