THE NAUTILUS. 31 



NOTES. 



MITRA AMANDA: A CORRECTION. 1 In my little preliminary 

 paper "New Marine Mollusks from the Philippine Islands," 

 Proceedings of the Biological Society of Washington, volume 

 31, pp. 181-188, December 30, 1918, I published Mitra amanda 

 new species from the Philippines, type Cat. No. 221815, U. S. 

 N. M., collected by the author at Dumurug Point, Cataingan 

 Bay, Masbate. 



In monographing this group I note that the same combina- 

 tion was used by Lowell Reeve, Proceedings of the Zoological 

 Society London, 1842, p. 59, and Conchologica Iconica, 1845, 

 species number 318, type "from the islands of Burias and 

 Negros, Philippines," now known as Turricula amanda Reeve. 



It is therefore necessary to bestow a new designation on my 

 shell, which may now be known as Mitra dgna. PAUL BARTSCH. 



OPEAB PUMILUM PFR. IN PHILADELPHIA. This snail has been 

 living in the decayed boards of fences at the rear of the houses 

 in the 1800 blocks of North 17th and N. Willington Streets for 

 some time. I found the first specimen in 1917 and collected 

 eight others April 30 and May 22, 1919. It may be of interest 

 to record this West Indian species as it is new to Philadelphia. 

 The colony is in the built-up part of the city, at the sides of a 

 cemented alley and not near any hothouse. The animal ex- 

 cretes a white froth like soapsuds when it retracts into the shell. 

 The eyes are very small and black. The body of the living 

 specimens is pale yellow in color, with lighter tentacles. They 

 are quite active in daylight after a rain. E. G. VANATTA. 



DR. HERMANN VON IHERING, formerly Director of the State 

 Museum of Sao Paulo, Brazil, has accepted the position of 

 Director of the State Museum of Sta. Catharina, to be organized 

 by him. During the last few months he has been sent by the 

 government on a scientific expedition to Argentina and Chile, 

 charged with the study of the fishes and fisheries of these Re-
