A single specimen, an immature male, 700 mm. in total 

 length.

 Africa, but has not been recorded from South Africa. 



4. Trygon margarifa, Giinth. 



5. Ehps lacerta, Cuv. & Val. 

 6. Clupea dor sail's, Cuv. & Val. 



7. Pellcnula tor ax, Gunth. 



8. Arius heudelotij «Juv. & Val. 



A specimen of 300 mm. is the first example of this species 

 to reach the British Museum. According to the original 

 description, " Les plaques palatines sont trfes-^cartees et tr^- 

 pctites"; in the present example there is a very small patch 

 of teet'i on one side of the palate, but none on the other. A 

 related species, A. parkii, Giinth., has been placed in the 

 synonymy of .^. A«M</^/o/i by Boulenger (Cat. Afr. Fish. ii. 

 p. 387), but differs from it notably in having two compara- 

 tively large patches of teeth on the palate, separated by an 

 interspace much less than their own width. In addition the 

 mouth is narrower (piffMnaxillary band of teeth four times as 

 lung as broad in A. i^arkii, seven times in A. heudtlofi), the 

 fkuU is less coarsely granular, &c.

10. Murcenetox ferox, Costa. 



Two examples, 800 and 1200 mm. in total length, show 

 that this species, originally described from the Mediterranean, 

 is quite distinct from the American M. savanna, Cuv. The 

 vomer is armed with a series of 11 to l.'i teeth, which ends 

 poalcriorly nearly at the level of the anterior edge of the eye;
