raidway between the root of the caudal and the opercle, a little 

 nearer to the latter. The origiii of the dorsal fin is a little 

 anterior to the origin of the anal fin in the male, in the female 

 a little posterior to the same. The total length of the male 

 including the caudal fin is 111 mm. without caudal 78 mm. 

 The length of the female without the caudal fin 68 mm. The 

 length of the head is contained in the length of the body without 

 the caudal fin 3,7 — 3,6 times. The length of the snout is con- 

 tained in the length of the head about 4 times. The diameter 

 of the eye is contained about 4 — 4,2 times in the length of the 

 head. The interorbital space 2,3 — ^2,4 in the same length. 



Number of scales in the lateral line 35 + 3, in a trän sv . 

 line 11. 



The lower jaw projects beyond the upper. The outermost 

 series of the teeth is strongly developed, conical and curved 

 inwards. Behind the rather broad band of small villiforra teeth 

 there is in both jaws a second series of enlarged teeth, but these 

 are not so large as the outer. The strong development of the 

 teeth indicates Fundulus Sjöstedti to be a fish of prey. The in- 

 testinal tract is short. 



Fundulus Sjöstedti is related to F. orthonotus (Peters) 

 Günther, but the number of rays in the fins, as well as the 

 number of scales in the lateral line is difterent. Besides all the 

 anal rays of the female of F. Sjöstedti are articulated and the 

 coloration as well is different in both species. 



F. orthonotus is known from the east coast of Africa. 



Syngnathua kaupii Blecker. 



A specimen of about 10 cm. length was caught at the 

 Ekundu factory in the Cameroons, in a small rivulet, which 

 running through the bushes empties its water in the mangrove- 

 region, from where the Syngnathus had ascended. But when 

 caught it lived in fresh water. 



Total length with the caudal fin 99 mm. 



Length of the caudal fin 4 mm. 



Length of the head .14 mm.
