side gently curved, lip much involute. H. 60 uiillini., br. 19 mill., length of body 

 whorl 35 mill., width of same 6 mill., length of aperture 29 mill., width of same 8 

 millim. 



Abundant at Lansa and other places in FarO, at Wialmsudd in Bunge, in the 

 canal from Stormyr in Rute, in Martebo, in the shale beds of Wisby, \Yestergarn and 

 Gnisvard. 



The specimen delineated on plate XV tig. 48 deviates thus far, that it is more 

 slender and the whorls relatively much longer than wide, but as there is only one 

 specimen as yet found, I cannot ascertain if it is a distinct variety or species. 



Gen. EUCHRYSALIS Laube. 



Eitclwysalis 1868. Laube Deukschriftcu der Akacl. der Wissenscli. in 'Wien 2e Abllieil., 69. 



Shell elongati', widest at the middle of its lencith, ichorls short and numerous, smooth 

 and glossy, suture shallow, the aperture long, narrow, outer lip sliarji and thin, the inner 

 lip involute as in Daphnella, ending upwards in a very shalloic notch. 



After having compared specimens of Euchrysalis fusiformis Muxster from St. 

 Cassian with specimens from Gotland described below, I cannot but think that they 

 all belong to the same genus. The Silurian species deviates, however, from the Tri- 

 assic ones in having a fine sculpture on the glossy surface. The chiiracteristic form 

 of the aperture and the general shape of the shell itself is quite identical. No species 

 seem hitherto to liave been found in the Devonian and Carboniferous formations. 



Euclirysalis lineolata n. 



Fl. XVIII tig. iVo—f,^. 



Shell conical, tapering, slender, acuminated and straightly grown, with nine whorls, 

 regularly increasing in size, the body wdiorl being only twice as large as the next pre- 

 ceding. The whorls are only slightly convex or tumid around their middle and the 

 suture is not much impressed. The surface is sculptured by perpendicular, equidistant, 

 minute ridges, which have their inner side thrice as large as the exterior one. For 

 the rest the surface is smooth. The aperture is, as far as visible, elongated and poin- 

 ted below, widened above. The columellar lip is involute and the siphonal notch, 

 above, only just perceptible. H. lo millim., br. 4 mill. Another specimen: h. 18 mill., 

 br. 4 mill. 



A dozen specimens have been found in the beds of the red and gray limestone 

 of the hills Sandarfve and Linde.
