155. Genyatremus luteus (Bloch). 



A small specimen, 2 inches long, was taken in a tide pool at Natal. It 

 differs from one 6 inches long from Bahia (Albatross Collection) in having 

 the preopercular teeth much, coarser, or about 12 of them rather than 21 as 

 in the larger one, the caudal truncate, rather than concave, the posterior 

 outlines of the dorsal and anal more nearly vertical, and in having 6 wide, 

 dark cross bars in the side. 



Family SPARID^. 



156. Calamus calamus (Cuvier and Valenciennes). 



Several specimens were taken by a steam trawler a few miles off Natal. 

 In life this species is a bright silvery with delicate blue, green and yellow 

 reflections most conspicuous on the snout. A clear blue streak runs from the 

 upper end of the gill opening forward below the eye. (In preserved speci- 

 mens this shows as a dark blue streak below the eye, but not extending past 

 the eye either before or behind) . Below this, running forward on the pre- 

 opercle, are several pale blue, obscure, wavy lines. Sometimes these are 

 dusky blue and run together more or less, forming a net-work around the 

 gold and silvery color, as described in current descriptions. Many of the 

 scales are bright blue at the center, making faint longitudinal lines. 



157. Archosargus unimaculatus (Bloch). " 



A single small specimen was taken at Natal. 



Family GERRID^. 



158. Euclnostomus pseudogula Poey. 



Specimens collected at Natal and Lake Papary. Among the former is 

 one with only two anal spines that dift'ers in no other respect from its fellows. 



159, Euclnostomus harengulus Goode and Bean. 

 A few small specimens taken at Natal. 



160. Euclnostomus gula (Cuvier and Valenciennes). 

 A single small specimen was collected at Lake Papary. 

 161. Ulaema lefroyi (Goode). 



This species, though unrecorded from Brazil, is not uncommon at Natal, 

 where several small specimens were taken. The young are marked with ir- 

 regular, oblique, broken blotches on the back extending forward and down- 

 ward to the middle of the side.
