G. Pctterdi and many that were supposed to be restricted in their 

 habitat to the southern part of the Island, have been found to be 

 generally diffused. 



In conclusion, I must congratulate the author on the excel- 

 lence of his paper, and I hope other observers in various parts of 

 the world will take this important matter in hand and still further 

 elucidate the '•Geographical Distribution of Terrestrial Mollusca."

The Marine Shells obtained during the "Chevert" 

 Expedition. — By John Brazier. 



(From r>vc. Lin. Sth., X.S.JV., 1S76. ) 

 The activity of Mr. Brazier during the voyage of the 

 "Chevert" may be gleaned from the fact that in the four notices 

 of the marine shells obtained^ published up to the present, no less 

 than 305 species are recorded. 



This rich harvest has not only added in a great degree to our 

 knowledge of geographical distribution in this comparatively 

 unknown region but a number of very interesting and novel 

 species have been discovered and are described by the author, 

 viz. :— 



Drillia A/astersi, Spaldingi ; ClatliunUa Ranisayi., Baniardi, 

 Maclcayi^ tricolor ; Murex exiiniiis, Ochiehra confi/sa, Epidromiis 

 Angasi ; Marginella hevigata ; Anacliis dathrata ; Aiiiyda viaricc, 

 inscripta, t)ierita,piidiia, abyssiada ; Astyris lata ; Turbcnilla Darn- 

 hyeiisis, cxi/nea, opiini, coiifusa ; Odosioinia clara, aj/inis, ccmpta, 

 polila, parvida ; and Syniola puldira. 



In addition to this lengthy and interesting list of new species 

 24 others are mentioned, of which only single or mutilated 

 pecimens were obtained.
