' ^ZOOLOGICAL SERIES OF FIELD MUSEUM OF NATURAL HISTORY Volume 24 CHICAGO, SEPTEMBER 19, 1939 No. 8 MALACOLOGICAL NOTES BY FRITZ HAAS CURATOR OF LOWER INVERTEBRATES FIRST ILLINOIS RECORD OF A JAPANESE POND SNAIL On November 18, 1938, I found a dead, not full-grown but identifiable specimen of Cipangopaludina malleata Reeve, in the outer lagoon in Jackson Park, Chicago. It is entered in Field Museum Cata-logue as No. 11438 and is figured here-with (fig. 7). I am indebted to Mr. E. Strandine, of Northwestern University, and to Mr. F. C. Baker, of the University of Illinois, for the statement that to their knowledge this species has never been recorded from Illinois; nor does it seem to have been found in the adjacent states. This Japanese in-truder has hitherto been known only from maUeafa cago; Field Mus. No. 11438. O n the Atlantic THfcUi^ARireCBflto of the species in the Unj^'pttes^ggbe found in various volumes of The Nautilus. UNIVERSITY OF ILLINOIS REVERSED SPECIMENS OF CAMPELOMA FROM THE CHICAGO AREA Some information concerning reversed specimens of shells belong-ing to the genus Campeloma Rafinesque has been assembled by F. C. Baker in his Fresh Water Mollusca of Wisconsin (Bull. Wis. Geol. Nat. Hist. Surv., 70, 1928). Additional data recorded here refer to the species integrum Say and decisum Say. Baker (I.e., p. 67) says with reference to Campeloma integrum that he found only one reversed specimen among 160 normal ones, and that none were seen as embryos. Field Museum has one reversed female No. 450 93
