ward. Scales of the body considerably larger than in Xiphostomu. 

 Lateral line incompletely developed. 



An excellent finnre is given by Doctor Steindachner in the paper 

 cited above (Plate XIII, fig, 2), and the species, which is called 

 inscul'ptus., is fully described on pages 51-53. It is very similar to 

 hujeta, differing mainly in the depth of body, and may be identical 

 with that species. 



C. maeiilafiis, another species of this group, has 88 scales in the 

 lateral line, being intermediate in this respect between C. hujeta and 

 the many-scaled species cuvieri and oeellatum., which have 105 to 106 

 scales. 



The following genei*a are now included in the subfamily Xiphos- 

 toniincE :

Judging from the illustration of Xiphostoma cuvieri,, in Spix's 

 Pisces Brasilienses, Plate XLII, all species coming under the sub- 

 family XipJiostomince probably have pectinate scales. In a recent 

 letter, Dr. C. PI. Eigenmann says that there is no doubt that the 

 genera Cfcnolvrivs, Luciocharaoc., and Belonochara.r are identical. 

 He examined the types of hiijefd and i/isrulpfus while in Europe last 

 summer, and has little doubt tliat they represent the same species. 



The following notes are taken from two specimens of Ctcnolucius 

 hujeta preserved in the collections of the V. S. National Museum, be- 

 ing the examples mentioned by Doctor Gill in 1861 :
