144 THE NAUTILUS. 



All these shells are in the collection of the Academy of 

 Natural Sciences of Philadelphia. E. G. VANATTA. 



The table of Winnecook, Montana, Mollusca, which was of- 

 fered in my paper in the March Nautilus (p. 125), suffered edi- 

 torial deletion of two of its original columns of data. 1 From the 

 list as printed it would appear that my subsequent note on the 

 coincident occurrence of Sucdnea oregonensis and S. avara was 

 based on the discovery of but a single specimen of each. It 

 should be stated that in 1913 both species were found living to- 

 gether in some numbers. The specimens differed with absolute 

 uniformity in both animal and shell and there were no inter- 

 grades. 



On p. 127 occurs a lapsus calami of my own : July 4, 1915 is 

 the correct date for the collection in Swimming Woman Creek 

 Canyon. S. S. BERRY. 



CYPRAEA VENUSTA var. BAKERI, Western Australia, and C. 

 MILIARIS var. GABRIELI, Northern Territory, Australia, are new 

 cowries described and figured by Mr. J. H. Gatliff, in The 

 Victorian Naturalist for February, pp. 147-149. 



Mr. Frank C. Baker, Zoological Investigator for the New 

 York State College of Forestry at Syracuse University, addressed 

 the Syracuse Chapter of the Society of Sigma Xi on February 

 25; his subject was "The Relation of Mollusks to Fish in 

 Oneida Lake." The address embodied an outline of the 

 biological survey carried on during the fall of 1915 by Doctor 

 C. C. Adams, Professor T. L. Hankinson and Mr. Baker, the 

 ol jcct sought being to ascertain the fitness of this largest of 

 New York's inland lakes for the maintenance of fish fauna. 

 At this meeting of the Society, Mr. Baker was installed as an 

 active member of the Syracuse Chapter of Sigma Xi. 



1 The two columns deleted merely recorded the species taken in two years 

 preceding those in the printed record, without indication as to abundance, 

 association or any other data. As all appeared also in the subsequent 

 records the Editors failed to see their importance.
