III. Sub-sect. FORMOSANA, Bttg. 



14. Clatjsilia Magnaciana, Heude. 

 Heude, Moll. terr. p. 66, t. xx. fig. 3. 



Judging from a typical specimen sent by Pere Heude, this species 

 is very similar to C. pacifica, Gredl., but differs in having a more 

 strongly developed lamella superior which is separated from the 

 lamella spiralis, whilst in C. pacifica the lamella superior and 

 lamella spiralis are distinctly continuous. The lamella inferior is 

 more distant fi*om the lamella superior, and there is a notch in 

 the peristome above the lamella superior ; there are only four 

 genuine plicae palatales, and finally the plica principalis ends 4 mm. 

 distant from the peristome, whereas in C. pacifica it is only 2 mm. 

 from the margin. One step further in the development of the lamella 

 inferior leads us on to C. artifina, Heude, and C. gigas, Molldff., 

 which two species must therefore be included in the section Formosana. 

 We do not concur in Mollendorff's opinion. 



The dimensions of the type specimen are as follows : alt. 26 mm ; 

 diam. max. 6'3 mm. 



15. Clatjsilia gigas, Molldff. 



Yon Mollendorff, Jahrb. d. d. Mai. Ges. 1886, p. 200, t. vi. fig. 8 ; 

 Heude, Journ. de Conch. 1886, p. 299, and Moll. terr. p. 156, t. xxxiv. 

 figs. 11, 16 (C. lahrosa et C. indurata). 



This species was found by Mr. Bock's collectors at Changya : alt. 

 28-6 mm. ; diam. max. 75 mm. (7 whorls); alt. 35 mm. ; diam. max. 

 8-3 mm. (8J whorls). They are all decollated. 



Judging from original specimens in our hands, C. gigas^ Molldff., 

 and C. lahrosa, Heude, are identical, and as Heude himself has 

 declared C. lahrosa to be synonymous with his C. indurata, it follows 

 that C. gigas and C. indurata are one species, and Mollendorff's name 

 has the priority. Both species were published in 1886, but Mollen- 

 dorff's was figured, whilst Heude's figure was only given in the third 

 volume of his " MoUusques terrestres," etc., which was not brought 

 out until 1890. Besides, as Heude's C indurata and C. lahrosa were 

 described in the fourth part of the Journ. de Conchyliologie for 1886, 

 it is probable that they were' actually published some months later, as 

 the Journal is generally late in its appearance.
