ANNULARIA (LUGARENIA) NAJAZAENSIS PALOMARENSIS. new subspecies 



Plate 47, Figure 8 



This subspecies comes from Palomar de San Jose, Camagiiey 

 Province. It is easily distinguished from A. (L.) najazaensis naja- 

 zaensis by its smaller size, by its little more slender form, and by 

 having the nodulations near the smnmit of the whorls more pronomiced 

 and the spiral sculptm-e less strongly developed. 



The type, U.S.N.M. No. 493505, has 6.1 whorls and measures: 

 Length, 13.1 mm.; greater diameter, 9.5 mm.; lesser diameter, 7.0 mm. 



ANNULAHIA (LUGARENIA) LIRATA, new species 



Shell of elongate-turbmate outline, pale yellow, with feebly expressed 

 interrupted spiral bands of brown, of which the one a little below the 

 periphery seems most pronounced. There is also a dark spot in the 

 suture of the nucleus. Nuclear whorls 2, well rounded, smooth, form- 

 ing a somewhat depressed apex. Postnuclear whorls inflated, strongly 

 roimded, marked by retractively curved, sublamellar axial riblets, which 

 are rendered nodulose by spiral threads. The nodulation varies in 

 strength in the different subspecies. Suture very strongly constricted. 

 Periphery mflated, well rounded. Base short, openly umbilicated, 

 marked by the continuation of the axial ribs and by spu'al tlu'eads 

 which here become a little stronger than they are on the spire. On 

 the umbilical wall the spiral tlu'eads increase m number but are 

 reduced in strength. The last whorl is adnate. Aperture broadly 

 ovate; peristome double, the inner reflected and more or less adnate 

 to the outer; the outer rather broadly expanded, somewhat fluted, 

 and marked by concentric lines of growth. Operculum typically 

 lugarenid. 



Tliis species comes from the Sierra de Guaicanamar. 



We are recognizing two subspecies, which the following key will 

 help to differentiate: 



KEY TO THE SUBSPECIES OF ANNULARIA (LUGARENIA) LIRATA 



Nodulation on the last whorl strong lirata 



Nodulation on the last whorl feeble parva 



ANNULARIA (LUGARENIA) LIRATA LIRATA, new subspecies 



Plate 47, Figure 1 



This subspecies was collected by P. Sifontes at Guaicanamar, 

 Camagiiey Province. It can easUy be distinguished from A. (L.) 

 lirata parva by its larger size and much stronger nodulation. 



The type, U.S.N.M. No. 493507, has 6.0 whorls and measures: 

 Length, 13.0 mm.; greater diameter, 9.8 mm.; lesser diameter, 7.8 mm.
