is a feature conforming with that of erythrophthalmv s . and 11 rays cannot be regarded a rare value as stated by the description. Even the raye of the pectoral fins confrom with those of erythrophthalmu s , since in none of my specimens did I find 13 rays, but assuredly 15 in one of them. Nor do the numbers of the undivided and divided rays of the ventral fin confrom to the data of the original description, because I found 2 undivided rays in every one of my specimens, while the number of the divided rays were 8 in all cases, instead of being 9 as stated in the description of the species. The scale numbers of the lateral line of my animals also disagree with the data of the description,since the frequentest value ought to be 41-43, and they are 39-41 in my specimens, ­again utterly conforming with those of erythrophthalmu s . Examining only one specimen, the number of the branchial spines was 11, the value corresponding with both forms. As regards the data of the corporal measurements, the description of the species states that the body height of the new species is lower than that of erythrophthalmu s , but MÜLLER gives the values in a reverse order, since, according to him, the greatest height of erythrophthalmu s varies between 27,6-30,8 %, M. 28,4 while that of racovitzai between 28,3-34*7 M. 32,1 %. There must be some error here, since in this way there is a contradiction between the text and the table. According to my own measurements, the greatest body height of erythrophthalmu s is between 32,0­37,2 M. 35,1 while in the 5 racovitza i specimens,it is 28,3-31,2 %, M. 29,4 %. This difference between the two is definitely significant. The length of the head in erythro­phthalmu s is 22,5-25,2 %, M. 23,6 and in racovitza i 26,7­29,9 %, M. 28,5 also a significant disparity. Also, the data of the length of the caudal peduncle differ, 17,6-20,4 %, M. 19,2 % in erythrophthalmu s, and 13,7-17,0 %, U. 15,3 % in racovitza i. The description shows yet differences in the length of P. and the diameter of the eye, but the values
