GENERAL NOTES. 



POLYGYRA TRIODONTOIDES IN NEW MEXICO. Prof. J. D. Tins 



ley has just brought me several specimens of P. tridontoides Bland, 

 which he collected this year on South Spring Creek, near Roswell, 

 in the Pecos Valley. This adds a species to the fauna of New Mex- 

 ica, and extends its range considerably to the west. T. D. A.

THE MOLLUSCA OF FUNAFUTI. By Chas. Hedley. (Memoirs 

 of Australian Museum, III., 1899.) 



Several expeditions have recently been made to the Ellice Islands, 

 in which is situated the Funafuti Atoll; In his introductory remarks 

 Mr. Hedley says : " The poverty of the fauna of the atoll, compared 

 with that of any continental area lying under corresponding latitudes, 

 such as Queensland, New Guinea, or the Melanesian Plateau, again 

 asserts itself. Whole groups, the Brachiopoda and the Polyplacophora, 

 are missing, giving to the fauna an unsyminetrical aspect. Especi- 

 ally significant is the absence ot mollusca with large eggs, such as 

 Nautilus, Melo or Voluta, from this drifted fauna. In many cases the 

 Funafuti shells are smaller than the usual stature of their respective 

 species." 



"It comes as a surprise to a naturalist to find the pelagic fauna 

 scarce in this latitude. One Pteropod, one Ileteropod, and a frag- 

 ment of lanthina were all of this class that came under my notice. 

 The quiet waters of the lagoon prove a richer field for a collector than 

 the storm-swept ledges of the ocean beach. The sole representative 

 of a fluviatile fauna was a species of Mela/ita, which occurred in some 

 abundance in the native wells." 



Part I. contains the- Gasteropoda, Part II., the Pelecypoda and 

 Brachiopoda, followed by a summary of the entire fauna, and later 

 by "a supplement. 



Four new genera, Obtortin, Contnmax, Thetidos and Mecoliotia, 53 

 new species and four new varieties of Gasteropoda ; G new Pelecy- 

 poda, one new Scaphopoda, and one new Brachiopoda are described. 

 Upwards of G50 species are recorded from the atoll.
