EUDULITS gen. nom. nov. 

 Tj^De Dules auriga Cu\'ier. 



The species of this genus are close to Prionodes Jenyns, but differ in 

 having 6 branchiostegals and a truncate caudal. The typical species, 

 Eudulus auriga, has the third dorsal spine whip-like and prolonged. 



In the Proc. Acad. Nat. Sci. Phila., 1907, p. 150, Dr. Theodore Gill 

 has taken exception to my contention that his genus Kuhlia is super- 

 seded by Dules Cuvier and evidently that Dides malo A^alenciennes is 

 older than Dides mato Lesson. Although my conclusions will now 

 be found to agree somewhat with Dr. Gill's they are the results of 

 different methods. For those who contend that Dulus Viellot, 

 Anal. Ornith. Element., 1816, p. 42, proposed for a genus of birds, and 

 Dules Cuvier, Regne Animal, Ed. 2, II, 1829, p. 147, are different names, 

 Dules will still be fovmd available in place of KuJdia. This led me to 

 frame Duleidoe, rather than Dulidoe, as emended by Dr. Gill. In the 

 Foreign Quarterly Review for January to March, 1829, vols. I, II, IV 

 and V of Regne Animal, Ed. 2, are reviewed, and volume III is said to 

 be delayed a few months. In this journal for 1830 volume III is seen 

 to have at last appeared. Still further evidence is found for the 

 early appearance of Cuvier's Regne Animal in Ferrusac's Bull. Sci. 

 Nat. GeoL, Paris, XVIII, 1829, p. 95 where it is noticed by July. 

 According to this last, in vol. XIX, 1829, p. 369, is found the first 

 mention of vol. Ill, Hist. Nat. Poiss., showing it and the succeeding 

 volumes had not been received till November or December. Cuvier's 

 footnote in the Regne Animal to "Dules auriga Cuv. et. Val., Ill, li; — 

 D. tceniurus, ib., liii," etc., does not prove that they really did appear 

 before the work in which they are quoted, thus leaving both of these 

 names nomina nuda and therefore either not available as the type. 

 In the bound copy of the plates before me only two species are shown, 

 and both numbered 52, though the first has been corrected by the 

 engraver as 51 for Dules marginatus and 52 allowed to remain for D. 

 auriga. The next plate or 53 is Therapon theraps. The evidence I 

 have gathered may be seen to have justified Dides Cuvier^ replac- 

 ing Kuhlia Gill, though I now consider the former preoccupied. 



In the case of Kuhlia malo Lesson's work may have probably appeared 

 later, as in An. Mag. Nat., London, (7) XVII, 1906, p. 336, Messrs. 

 Sherborn and Woodward make corrections to a previous paper on the 

 dates. This would carry the reference to Dules mato back to No veni- 

 re ' The species originally noted under this name by me may now be known as 

 Kuhlia marginala, K. marginata boninensis, K. rupestris and K. malo.
