always reach the base of the body-whoii — in fact, in a long series 

 hardly two specimens are alike. The one selected for the type is an 

 average specimen in most respects, although perhaps rather more 

 ventricose than many. 



Glandina Bogotensis, n.sp. PI. I, Fig. 5. 



Testa fusiformis, crassiuscula, nitida, purpurascenti-castanea ; spira 

 elongata ; anfractus septem, convexiusculi, longitudinaliter creberrime 

 plicato-striati, sub lente minute transversim ^triuti, ad suturam 

 subtiliter crenulati, et anguste marginati; columella fere recta, 

 albida, couspicue truncata ; apertura parviuscula, purpurascenti- 

 castanea; labrum pallidum, ad marginem subincrassatum. Long. 51, 

 diam. 21 mm. ; apertura 21 mm. longa, 10 lata. 



Hah. — Bogota, Colombia. 



A few specimens of this shell reached the writer several years ago. 

 It is closely allied to G. cequatoria,^ Da Costa, from Ecuador, but is 

 more fusifi)rm, thinner, has a whorl less, and is without the transverse 

 striation of that species. 



Streptostyla Costaeicensis, n.sp. PI. I, Fig. 3. 



Testa cylindraceo-oblonga, tenuis, pellucido-cornea ; spira brevis, 

 ad apicem obtusa ; anfractus 5.^, subplano-convexi, ad suturam 

 marginati, Iseves, politi ; columella brevis et contorta ; apertura 

 oblonga, anguste auriformis, labro in medio impresso, ad marginem 

 albo. Long. 19, diam. 9 mm.; apertura 13 mm. longa, 3*5 lata. 



Hai. — Azajar de Cartago, Costa llica. 



This shell was collected by Mr. Underwood in 1896, and is one of 

 two specimens in the writer's collection. It much resembles 

 S. cylindracea, Pfr., but is more ovate and has a shorter aperture. 



Neooyclotus Panamensis, n.sp. PI. I, Figs. 6-9. 



Testa aperte umbilicata, depressa, lutescens ; anfractus 4 J, rotundati, 

 incrementi lineis striati, et obscure retuse corrugati ; peristoma tenue,

 ad suturam filo -carinatum, in medio concavum. Diam. maj. 15, 

 min. 12 mm., alt. 10 mm. 



Hah. — Chiriqui. 



There are some unnamed specimens in the British Museum from 

 Panama which are identical with this species.
