24 SYKES : CLAUSILIAE FROM CELEBES. 



but the shell is slightly more solid, the mouth more ovate and 

 not nearly so oblique, the lamella inferior not so strongly twisted 

 spirally, but more rapidly ascending into the shell. 



I have also what I take to be a small variety of this species 

 measuring alt. i2-2, lat. 2-9 mill. ; alt. apert. 2-9, lat. apert. 

 2 mill. (Plate IV., Figures 5 and 6). 



In this form the lamella sub-columellaris is almost obsolete, 

 as is also the smaller palatal plica, and the mouth is more 

 quadrate. It was collected with the type and will, I think, 

 prove to be only a variety and not a distinct species. 



The species recorded from Celebes appear to be as follows : 



C. cumingiana, Pfr., var. moluccensis von Martens. 



N. and S. Celebes. 



C. celebensis, Smith. Bonthain Peak, 5000 to 6000 ft. 



C. smillima, Smith. S. Celebes, 2000 It. 



C. suhpolUa, Smith. S. Celebes, 2000 ft. 



C. iisitata, Smith. S. Celebes, 2000 ft. 



C. celebensis, Boettger. Balante, E. Celebes. 



C. alternata, Moellendorff. Bua Kraeng. 



C. viakassavensis, n. sp., near IMakassar. 



C. pyrrha, n. sp., near Makassar. 



Inasmuch as there are tw'o apparently distinct species both 

 published under the name of celebensis, it becomes material to 

 ascertain which has the priority in date. 



Mr. Smith's species appeared* on July 25th, 1896. Dr. 

 Boettger's species appeared in a paper by Dr. Kobelt entitled 

 " Schnecken von N. O. Celebes and Banggai,"! without, it may 

 be remarked, any figure. This publication bears at its foot the 

 date " 27th June, 1896," and this is, one would suppose, the date 

 of publication. An enquiry in April, 1897, however, from 

 Messrs. Friedlander, whose name appears on the title-page as 

 publishers, yields the following : — " No. 5 was published in 

 October, 1896 (see our ' Naturae Novitates, 1896, nr. 20.') " 



The date on the publication, therefore, appears to be that 

 either of reading, or of distribution of reprints, and the note 

 in the Nachrichtsblatt t that " Die Clausilie wird vor der 

 gleichnamigen Smithschen Art wohl einige Tage Prioritat 

 haben " is inaccurate. 



In such a state of aftairs Dr. Boettger's species requires a 

 new' name, and I would propose that of balantensis.
