CHIMiERID^J. 



Chimaera novae-zealandiae nom. nov. 



For C. monstrosa var. australis Hector, Trans. N. Zeal. Inst., XXXIV, 1901 

 (1902), p. 239, PI. 14, fig. 3, preoccupied by C. australis Shaw, Gen. 

 Zool., V, 1804, p. 36S, Pis. 158, a synonym of Callorynchus. 



Of this family only two species are represented in our collection, 

 C. monstrosa (L.) from Italy, and Hydrolagus colliei (Lay and Bennett) 

 from Pacific Grove, Cal., and Alaska. I wish to call attention to the 

 name Chimcera neglecta Ogilby, in Appendix A, Rep. Com. F. N. S. 

 Wales, 1887 (1888), p. 23, which is preoccupied by C. neglecta Egerton, 

 Proc. Geol. Soc. London, IV, 1843, p. 153, for a fossil species. According 

 to Dr. Waite, C. neglecta Ogilby is thought to be identical with Hydro- 

 lagus colliei (Lay and Bennett), and had best be regarded as such, 

 unless found to the contrary, though so far as I am aware this is its 

 only occurrence in the Australian seas. If different, it requires a new 

 specific name.
