NOTES AND NEWS. 



The Nason Collection, — The University of Illinois has lately 

 acquired the collection of shells of Dr. Wm. A. Nason, of Algonquin, 

 Illinois. The collection numbers approximately 50,000 specimens, 

 representing 10,000 species. Among these are large series of the 

 species found in Illinois, together with many beautiful specimens 

 from various parts of the world. 



The Ancey Library The books and many of the papers of 



the late C. F. Ancey can be obtained from Mr. Gerat, 76 rue du 

 Faubourg St. Denis, Paris, France. 



Note on Ctpr^a gracilis, Gask. — A few months ago, among 

 some small shells from unknown localities which came into my 

 hands, there appeared a small cowry which for a time puzzled me 

 exceedingly, being very different from any of the species then known 

 to me. Upon careful study, however, in connection with the var- 

 ious monographs of the Cypmidae, it has proven unmistakably to 

 be the very rare Cypraea gracilis^ Gask, the type of which was 

 brought from the China Seas by the " Samarang " and which has 

 since been found only at Mauritius and Reunion I. (WeinkauflF, 

 Hidalgo). Although the coloration of the back has been obliterated, 

 the specimen being beach-worn, it has the peculiar lip, the narrow, 

 bent aperture, sparsely scattered reddish-brown dots and fine teeth 

 called for in the Gaskoin description, and it also corresponds, as to 

 base and contour, to the figure in the Sowerby monograph, probably 

 copied by WeinkaufFand Roberts. Length, 10 mm.

NoTi! on Trivia maugebi^. Gray. — Of this very rare species 

 — sometimes also known as Tr. " Maugeri," (Roberts, Hidalgo) and 

 thus far found only at the Galapagos Is I have known but three ex- 

 amples in all the West American collections. The first which ap- 

 peared was a badly bleached one which I detected among the molluscan 

 material brought back by the Stanford University expedition of 

 1898, the specimen being now in the University collection. The 

 second, a fine one in the Arnheim collection at San Francisco, was 

 unfortunately destroyed in the great fire of 1906 ; while my own 

 specimen, although beach-worn, is in fair condition and color. 

 Length, 13 mm. — Fred L. Bctton.
