326 DR. O. BOETTGER ON NEW CLAUSILI^. [May 1, 



remained until recently unexamined, so that many species that were 

 unknown to science at that time have been since collected by others 

 and described. 



I have, however, now the pleasure of presenting descriptions and 

 figures of some 13 new species, as well as of about 18 new varieties 

 and forms, to the Society, out of the remainder of the Admiral's 

 collection, which he has recently submitted to me for that purpose. 



Sect. Albinaria, v. Vest. 



1. Clausilia anatolica. Roth. Dissert, p. 21, t. 2. fig. 5. 



Var. apicalis, mihi. 



Typo minor, spira hreviore, apice latissimo, obtusissimo. Anfr. 

 solum 8. Lamella infera intus minus distincte bifurcata. Alt. 

 14|, lat. A\ mm. ; alt. apert. 3|, lat. apert. 3| mm. 

 Hab. Arsa, valley of Xanthus, Asia Minor (Spratt). 

 The short form and the very thick apex distinguish this variety 

 easily from the typical 0. anatolica of Cacaino in Caria. 



2. Clausilia id^a, Pfr. P. Z. S. 1849, p. 140. 



This fine species, inhabiting Mount Ida, island of Crete, which 

 Admiral Spratt collected on the Plain of Neetha at 4000 feet alt., 

 must be registered between C.petrosa, P., and C. byzantina, Chrp,, 

 in the byzantina group oi Albinaria. 



3. Clausilia glabella, Pfr. P. Z. S. 1864, p. 604. 



I do not yet know the type of this species, inhabiting the 

 " White Mountains " at 6000 feet alt. (Spratt) ; but I am now sure 

 that my C. pura (Monogr. d. Claus.-Sect. Albinaria, p. 22, t.4. fig. 

 1) and" G. deglupta (I. c. p. 23, t. 1. figs. 2, 3), both Cretan forms, 

 are but varieties of Dr. PfeifPer's species. 



Var. PURA, Bttg. 



A typical specimen from Apokorona, island of Crete (Spratt). 



Var. sPRATTi, mihi. 



Typo midto major, cylindrato-fusiformis ; apert. intus hepatica. 

 Lam. supera longiuscula sed humilis ; subcolumellaris oblique 

 intuenti distincte conspicua. Differt a varietatibus pura, Bttg., 

 nee nan deglupta, Bttg., anfr. 13g, et lam. subcolumellari 

 haud inconspicua. Alt. 25|, lat. 4| mm. j alt. apert. 4|, lat. 

 apert. 3g mm. 



Hab. Island of Crete, without exact indication of locality (Spratt). 



This splendid variety, 5 mm. greater than usual, differs from all 

 varieties of this species till now known by its elongate cylindrical 

 form and by the distinctly outcoming subcolumellar lamella. 



4. Clausilia strigata, Pfr. P. Z. S. 1849, p. 136. 



A nearly typical specimen of this species, which had been found 

 till now in the neighbourhood of Mylopotamo, Rettimo, and Khania, 

 from the Omalo Plain at 3500 feet alt., island of Crete (Spratt).
