Thirty species arc euuincratcd tVoni Pahiwau or Para^ua, 

 and if Euplecta boholensis, PtV., be distinct from A\ ceOuensis, 

 ^Ollendorff, it will add one more to the total. It is quoted 

 from Palawan by Hidalgo*, but not in Cooke's paper. 



The most interesting addition to the fauna occurring in the 

 present collection is the new sjjecies of LatjocJiilus, a genus 

 hitherto unknown from Balabac or Palawan. It occurs, 

 however, sjiaringly in other parts of the Philippine group and 

 also to the south in Borneo &c.

This s])ecies is remarkable for the convex whorls and the 

 deep suture. It is of a rather rich brown colour on the upper 

 surface, but considerably paler beneath. The lines of growth 

 are rather strongly marked above, so that they present an 

 almost subplicate aj)])carance. The deep suture is bordered 

 with a very narrow dark brown line, which, however, is uot 

 noticeable without a lens. 



The genus Macrochlamys has not hitherto been recorded 

 from Palawan, but there are several allied species found in 

 North Borneo which have been placed in the section Everettiu 

 by Godwin- Austen (Proc. Zool. Soc. 1891, pj). 33-36).

 peUucida, nitida, cornea ; anfractus 5-6, lente accrcsccntea, con-

 ultimus ad peripheriam acute rotundatus ; spira breviter conoidea, 

 nd apiccra ol)tusa ; apertura oblique lunata ; peristoma simplex,
