projections in tlie sliapp of arrow-heads arise at right angfles

Diani, niaj. (with the peripheral wing) 14"5, alt. 4 mm. 



llab. Summit of Konahuanui, Oahu, Hawaiian Islands, 

 amongst dead leaves and moss. 



This very interesting shell was collected by Mr. Ernest 

 Lyman, and was kindly sent to me by Prof. H. W. Henshaw. 



It somewhat recalls in form and appearance the well-known 

 Helicina agglutinans, the periostracum covering the shell 

 and being produced into an uneven wing at the periphery, 

 some of the projections extending to 2 mm. from the shell. 

 The species belongs to the group of Amasira alata, Pfr., 

 and A. heliciformis, Ancey; from the latter, which is also 

 an Oahu shell, it may readily be separated, in addition to 

 its greater size and remarkable development of periostracum, 

 by its more depressed form and smaller (proportionally) 

 umbilical area. 



BIBLIOGllAPHICAL NOTICES. 



Tnflex Faiince Novce ZealamUce. Edited by Capt. F. W. Hutton, 

 F.R.S. Published for the Philosophical Institute of Canterbury, 

 New Zealand. London : Dulau, 1904. Pp. viii, 372. 



This is an extremely useful publication, and it is a great advantage 

 to have such an ludex to the natural productions of an area which 

 is sufficiently limited to admit of its being given in a moderate 

 compass. Captain Hutton's name is well linown to all students 

 of New Zealand natural history, and it is very creditable to the 

 colony that nearly all the other contributors to the volume are 

 resident in New Zealand.
