156 jotlRNAt OF CONCHOLOGY, VOL, 14, NO. 5, JANUARY, 1914. 



By Mr. G. C. Spence : Coelocentrunt gigas Pfr. ; C, ischnostcle Pils. ; C. hiiik- 

 leyi Pils. ; and rare species of the genus from Mexico and Peril. Also shells of 

 Urocoptis rosea from J. R. le B. Tomlin's collection to illustrate his note. 



By Mr. R. Standen : Umax niaximns var. vtaciilata Picard, beautifully pre- 

 served, showing the characteristic oblong, vivid black markings of this fine variety, 

 from Melmerley, Cumb. ; collected July 14th, 1913, by Rev. W. Wright Mason. 



By Mr. W. H. Ilealhcote : Juvenile forms of Zirfaa crispafa L., and Tapes 

 piillastra var. ferforans Mont, from chalk cliffs at Brighton. 



By Mr. T. H. Piatt : A beautiful series of Quadriila piistnlosa Lea, from Old 

 River, Arkadelphia, Arkansas ; Arcidens confragosiis Say, from Indiana ; and 

 Arkansia tuheeleri Ortmann and B. Walker. This latter species is a new Naiad 

 from Arkadelphia, Arkansas, and was brought to light by the Rev. II. E. Wheeler, 

 who is a resident of Arkadelphia. A description of this splendid species was 

 given by Dr. A. E. Ortmann and Bryant Walker in the January number of 77ie 

 Nautilus for 1912. The shell characters of this Naiad are quite distinct from any 

 other species, the nearest approach to it being Arcidens confragosus Say, but even 

 in this case the differences between the two species are decidedly marked, and the 

 one could never be mistaken for the other. For those who would like to look 

 further into the matter, the paper mentioned above will meet all requirements. 

 It gives a very full description of both the soft parts and the shell characters, with 

 some good comparisons with other genera and species, and there is also a beauti- 

 ful plate illustrating both the outside and the inside of the shell. Also a fine 

 specimen of Coehcentrufn gigas Pfr. var. and eggs of same from Guatemala 

 (coll. A. A. Ilinkley).
