316 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.55. 



other genera in the Pandarinae are distinguished chiefly by the char- 

 acters of the female, and the male plays an insignificant part in 

 genus differentiation. And even Dana's type males are lost, so that 

 they can never be identified with certainty. 



If Dana's genus is restored, therefore, we have a genus not yet 

 proved to be genuine, founded on the wrong sex, with the types lost, 

 and which can never advance beyond a probability until the other 

 sex is discovered. 



On the other hand. Heller's genus was founded upon two species, 

 the original female specimens of which are still preserved in the 

 Vienna Museum, and to them have since been added the males. Ac- 

 cordingly, while it may not be allowable to make Dana's genus a 

 synonym of Heller's, it certainly seems wise to retain Heller's genus, 

 because it has been definitely proved. We can leave Dana's genus 

 as it stands until female specimens are discovered, or until it can 

 be conclusively established in some other way. Let us not, even in 

 the cause of priority, sacrifice an absolute certainty for something 

 that can never be more than a possibility. 



LERNAEOPODA CLUTHAE. 



In volume 47 of these Proceedings an effort was made to locate 

 intelligently the various species belonging to the Lernaeopodidae. 

 One such species, Lemaeopoda cluthae, inadvertently appeared twice 

 under different genera. The allusions to it found upon pages 653 

 and 654 should be eliminated, while those upon pages 639 and 640 

 should be retained. 



LERNAEA ANOMALA. 



In the Bulletin of the Bureau of Fisheries, volume 35, there is de- 

 scribed (p. 194) and figured (pi. 14, figs. 68, 69, 70, 73, 74) a new 

 species of parasitic copepod under the name Lernaea anomala. When 

 this species was established it was placed in the genus Leriiaeocera, 

 as it then stood. It was afterwards found that the two genera must 

 be transposed in accordance with the laws of priority. The specific 

 name was all right as first established under Lernaeocera, but the 

 name Lernaea anomala was preoccupied by Abildgaard in 1794, and 

 although the creature he described did not belong to the genus Ler- 

 naea, nor even to the family Lernaeidae, it is still proper that the 

 name be changed. Accordingly the specific name insolens is sug- 

 gested in place of anomala, the two having the same meaning.
