96 THE NAUTILUS. 



I overlooked Mr. L. P. Gratacap's record of " Hare Island," St. 

 Lawrence River, given in his catalogue of the Bimiey and Bland 

 collection of the terrestrial air-breathing mollusks, etc. (Bull. Amer. 

 Mus. Nat. Hist., XIV, p. 39G, 1901). This species seems to be 

 more widely distributed than has been generally supposed. It is to 

 be hoped that these articles will lead to a still further knowledge of 

 its geographical distribution. C. W. JOHNSON. 



PUBLICATIONS RECEIVED. 



STUDIES ON AUSTRALIAN MOLLUSCA, PT. IX. By C. Hedley 

 (Proc. Linn. Soc., N. S. Wales, pt. iv, 1905). Twelve new species 

 are described and figured, with critical notes on other species. 



SOUTH AUSTRALIAN NUDIBRANCHS, AND AN ENUMERATION OP 

 THE KNOWN AUSTRALIAN SPECIES. By Herbert Basedow and 

 Chas. Hedley (Trans. Royal Soc., S. Australia, xxix, p. 134). 

 About 80 species are recorded, six new species described, and a 

 number of others redescribed and illustrated by 12 plates of beauti- 

 fully-colored figures. 



REPORT ON MOLLUSCA COLLECTED BY MR. HERBERT BASEDOW 

 ON THE SOUTH AUSTRALIAN GOVERNMENT EXPEDITION 1903. 

 By Charles Hedley (Trans. Roy. Soc., S. Australia, 19'5). A 

 valuable contribution to knowledge of the snails of the " Eremian 

 Region" of Central Australia. "Though quite unrelated to the 

 forms that people the arid regions of Asia, Africa or America, these 

 Australian shells ivpeat in their chalky texture and rough sculpture 

 the features of foreign species subjected to similar environment." 

 Several new species of Thersites and Xanthomelon are described, and 

 a beautifully-drawn plate illustrates the principal forms. 



A CATALOGUE OF THE MOLLUSCA OF ILLINOIS. By Frank 

 Collins Baker (Bull. Illinois State Lab. Nat. Hist., vii, pp. 53-136, 

 Sept., 1906). An excellent catalogue, giving in full the distribu- 

 tion of each species throughout the State. The number recorded 

 is 241 species of fluviatile and 91 species of terrestrial mollusks. A 

 very exhaustive bibliography is also given.
