58 LAURIA. 



pi. 8, f. 9. — Boettger, Jahrb. D. m. Ges., vi, p. 403 (Len- 

 koran) ; viii, p. 228. 



This species stands very near L. sempronii, but it differs, 

 as Boettger has pointed out, by the far stronger lamella run- 

 ning inward, and continuing as high within as at the aperture, 

 as seen in the obliquely basal view, fig. 5 ; the whorls are less 

 convex, the last one not so high. It is rather more openly 

 perforate. There is no columellar lamella. Possibly it will 

 be found to intergrade with sempronii, but at present it ap- 

 pears to be distinct. A Lenkoran specimen is figured. 



7. Lauria fanalensis (Lowe). PL 7, figs. 7 to 10. 



Allied to P. anconostoma. It differs by the shorter, more 

 obese and more ovate form, somewhat wider at base, the 

 whorls more convex, suture impressed, the- aperture rounded 

 basally, not angular, the ventral fold stronger, and the um- 

 bilical keel obsolete (Lowe). 



The shell is most minutely perforate and very shortly 

 rimate, very thin ; dilute, transparent isabella color ; glossy, 

 weakly striatulate. The whorls increase more rapidly than in 

 the short form of anconostoma. Summit obtuse. The last 

 whorl is well rounded basally, not compressed. Peristome is 

 narrow. Angular lamella small, slender, not connecting with 

 the outer lip-insertion. A low, thread-like columellar lamella 

 emerges weakly. 



Length 2.5, diam. 1.45 mm. ; 5 whorls. 



Length 2.4, diam. 1.5 mm. ; 4:% whorls. 



Madeira: at the Cruzinhas and the Fanal and Lombarda 

 das Vacas; in damp sylvan spots near the highest altitudes, 

 among moss and lichen on the trunks of laurels and on ferns 

 (Lowe and Wollaston). Canaries on Teneriffe in similar sta- 

 tions, wood of Las Mercedas; above Taganana, at the Agua 

 Mansa, and near Ycod-el-alto ; and Palma in the Barranco de 

 Agua, Barranco de Galga, and ascent of the Cumbre above 

 Buena vista ( Wollaston) .
