PLATE I. 



Steophocheiltjs (Eurytus) aukiformis, n.sp. PL I, Fig. 1. 



Testa acuminato-oblonga, vix umbilicata, tenuicula, fiilva, guttis 

 castaneis hie illic aspersis picta, subtilissime cornigata vel granulata, 

 epidermide tenui olivacea induta ; anfractus quiuque, oblique con- 

 voluti, sub piano convexi, longitudinaliter oblique granulato-striati, 

 sutura impressa sejuncti ; apertura ampla, auriformis, intus violascens ; 

 labrum valde expansum at reflexum, pallide violaceum ; columella 

 fortiter uniplicata, late reflexa, callo conspicuo dilute violaceo labro 

 juncta. Long. 74, diam. 38 mm.; apertui'a 43 mm. longa, 26 lata. 



Sah. — Bogota, Colombia. 



This species, of which only one specimen has been obtained, has 

 been placed in Eurytus on account of the granulated sculpture of its 

 surface and other characters peculiar to that section. It differs, how- 

 ever, from most other species in its very large auriform aperture. 



Strophocheilus Miersi, n.sp. PI. I, Fig. 2. 



Testa oblongo-ovata, vix perforata, solida, subventricosa, rosacea, 

 epidermide tenui luteo-olivacea induta, spira conica ; anfi-actus 

 quinque, vix convexiusculi, minutissime indentati, ad suturam 

 impressi, submarginati, ultimus descendens, basi rotundatus ; columella 

 alba, uniplicata, recedens ; apertura oblongo-auriformis, intus albida ; 

 peristoma album, incrassatum, expansum, et reflexum, margiuibus 

 callo albido junctis. Long. 72, diam. 35 mm. ; apertura intus 35 mm. 

 longa, 15 lata. 



Hah. — Minas Geracs, Brazil. 



This shell, which was acquired by the writer at the sale of the late 

 Mr. Miers' collection, bears a striking resemblance to S. contortu- 

 pUcatus, Kve. ; but differs from that species in many important 

 respects. It is more ventricose in contour, has no microspiral 

 striation, is more coarsely malleated, and the sutures are less im- 

 pressly marginated. 



Drym^us multispira, n.sp. PI. I, Fig. 4. 



Testa conico - ovata, vix umbilicata, tenuicula, albida, strigis 

 obliquis, f usco-nigricantibus picta ; anfractus 1^, convexi, laeves vel 

 rude striati, ultimus longitudinis ^ subaequans ; spira subacuminata ; 

 sutura impressa ; apertura ovata ; labrum simplex, intus plus minus 

 roseo tinctum ; columella reflexa, rosea. Long. 20, diam. 1 1 mm. ; 

 apertura 9 mm. longa, 5 5 lata. 



Eab. — Chuco Chaca, Bolivia, 4,000 feet. 



The shells of this species vary considerably both in form and 

 painting, some being more ventricose than others, while the longi- 

 tudinal stripes or blotches are more or less confluent, and do not
