TIIK XAITILUS. 11 



It was collected on a grassy slope, inclining to the northward, 

 and covered with grass, moss, and small bushes, and so far has not 

 been found anywhere else. Its permanent place in the system will, 

 of course, be determined by an examination of the soft parts, which 

 remains to be made. 



GENERAL NOTES. 



Owing to continued illness in his family, Mr. Campbell, President 

 of the American Association of Conchologists, has been unable to con- 

 tribute the monthly reports on Association affairs. He hopes to 

 resume them in the June issue. 



Mr. C. W. Johnson, Junior Editor of the Nautilus, and Mr. 

 Wm. Fox, of the Academy of Natural Sciences, have spent the 

 month of April in that paradise of land snails, Jamaica. They will 

 return about the middle of May, and doubtless bring with them 

 hosts of shells and insects. 



The personal interest felt by younger students in their predeces- 

 sors in science, is our excuse for clipping the following from a re- 

 cent letter : 



" In the March number of the Nautilus, Mr. Roper said that 

 Mr. ^Nlayo was probably the oldest student of conchology in 

 America. Mrs. Mary B. Allen King, of Rochester, N. Y., is 

 92 years old, having been born in January, 1799. She has studied 

 and collected shells before Mr. Mayo (whom she met at one time) 

 did ; and has corresponded with most of the U. S. Conchologists. 

 She was elected a member of the American Association for the 

 Advancement of Science in 1886, at the Buffalo meeting." — A. 31. K. 



Australian Slugs. — Mr. Charles Hedley exhibited and offered 

 some remarks on specimens of Vaginula leydigi, Simroth, and V. 

 hedleyi, Simr., two interesting slugs from Brisbane, recently added 

 to the molluscan fauna of Australia (vide Zoologischer Anzeiger, 

 1889, p. 551 ; and Abstr. in Journ. Roy. Micros. Soc, 1890, p. 21). 

 These slugs are very abundant in the Brisbane botanical gardens, 

 occurring also in lawns and gardens in that part of the city which 

 was formerly scrub land. After a shower they may be collected in 

 abundance, crawling rapidly over the asphalt paths and the grass. 

 V. leydigi is much commoner than V. hedleyi, which it resembles in 

 shape, size and habits, but from which its coloration distinguishes it 

 in all stages of its growth, the former being a blackish-brown with
