No. 21,563, A. N. S. P., type of H. Icevior Cope. Rio Jacuhy, 

 Brazil. H. H. Smith. Both this and the following species have 

 been merged with the preceding, though they appear to me distinct.

LORICARIIN.^. 

 Ehineloricaria ciadeae Hensel. 



Rio Jacuhy, Brazil. 

 Loricariichthys typus (Bleaker). 



Two examples, 208 and 224 mm. (caudal tips slightly damaged), 

 from Surinam. They agree with Bleeker's account^^ in having 

 14 caudal scutes, though Regan gives^^ but 10 or 11, which is in 

 agreement with Steindachner's figure of Loricaria stuhelii.-^ The 

 interorbital space, in my specimens, is flat, with the eye nearly 

 impinging on the upper profile of the head. In Bleeker's figure the 

 interorbital space is shown as elevated. My examples agree with 

 L. stubelii in their occipital armament, though ventrally they have 

 at least four rows of plates. In L. stubelii the figure shows the 

 median ventral plates absent in one case. Traces of dark spots are 

 also evident on the fins.
