Remarks. Pesta in his revision of the "Pengeidse" of 

 the Vienna Museum, separates his specimens of Trachy- 

 peneus into the two species, asper and'curvirostris, on the 

 basis of difference in direction and shape of the rostrum, 

 and the distinctness of the post-rostral carina. The 

 rostral distinctions he sets forth are entirely inadequate, 

 being included in any good series of T. currirostris: 

 and, too, his second diagnostic character is subject to 

 some variation. 



In the three "Endeavour" specimens which are here 

 assigned to T. curvirostris, as regards the indistinctness 

 of the post-rostral carina and the tendency toward longer
