894 NOTES AND EXHIBITS. 



an irregular median longitudinal blackish band sending off 

 branches to the legs, the remainder being dull rusty red or 

 brown. In all of them the transverse rows of papillifi on the 

 outer surface of the legs are pretty regularly alternately light and 

 dark coloured. The four spirit specimens are more or less similar 

 to one or other of the above described. On comparing our speci- 

 mens with Captain Hutton's description of P. N'ovce-Zealandice, one 

 is struck with the great resemblance, in respect of the external 

 characters. The only diagnostic characters mentioned in the 

 abstract of Sanger's paper (Arch. f. Naturg., xxxvii. Jahrg., II. 

 Bd., p. 406) are the presence of fifteen pairs of claw-bearing legs, 

 tlie situation of the generative aperture, and the characters of the 

 leg-pads; the latter, however, are not of specific importance, 

 Sanger's figure evidently having been drawn from a more or 

 less shrivelled specimen." 



Postscript. — When the above note was read I was not awai'e of 

 the publication of Mr. Sedgwick's monograph (Q.J.M.S., April, 

 1888), from which it appears that Queensland specimens differ 

 •somewhat in colour from those referred to above. My Gippsland 

 specimen was dead and dried up when T received it, hence it is not 

 in a very favourable condition for comparison ; but as far as I can 

 make out it is not unlike a much bleached example of one of our 

 dark specimens from Illawarra ; a whitish median dorsal line 

 visible in part of the body only is evidently due to bleaching, 

 though in the rest of its course a nodose black line is not well- 

 defined 



Mr. Sinclair exhibited portions of diamond-drill cores from the 

 Astoria works. East River, New York. 



Mr. Brazier exhibited a specimen of Physa gibhosa, Gould, 

 obtained more than a month ago in Waterloo swamps, since 

 when, though it had been merely left in a corked tube with a little 

 water, it had deposited a quantity of spawn. 



Dr. Cox exhibited specimens of a river-limpet (Ancylus Irvince, 

 Petterd), from a large lake in the interior of Tasmania. 



Also a Tertiary fossil from the Wild-horse Plains, which he 

 believed to be identical with Thylacodes decussatus, Gmel., a living 

 Port Jackson species.
