Note: This species is very near C. conspicillatns Jenyns 

 (Zool. Voy. Beagle IV. Fish. 1842, p. 14.7) = C. sealei Jordan 

 & Scale (Bull. Bur. of Fisheries XXV. (1905) 1906, p. 213). 

 The only real difference seems to be that its snout is still 

 more slender and conspicuously less than half the length of 

 the head. It seems to be restricted to the Pacific Islands 

 whereas C.fasciatus is a more western form. Perhaps DUNCKER 

 is right when he supposes that C. conspicillatns Jenyns is only 

 a local variety of C. fasciatus.

Syngnathtis crenulatus Max Weber, Siboga-Expeditie, Fische. 1913, p. 109. 



D. 2730; P. 14; Rings 15 17 + 35 40; subdorsal rings 

 i + 56. 



Extremely slender; trunk nearly four-sided, its height slightly 

 more than its breadth ; all the edges finely serrated, ending 

 on each ring with a prominent tooth, the fish therefore strongly 

 adhering. Head 7 8 times in length, more than twice in 

 length of trunk. Snout nearly equal to half length of head, 

 somewhat compressed ; its dorsal profile gently rising to the 

 orbits; its median crest ends in the narrow orbital space, 

 which is limited on both sides by a sharp supraorbital crest, 

 which is continued in a curve to the occiput. The occiput 

 with a sharp crest, which is continued on the nape. All crests 

 and edges on the head are serrated. Operculum with a rather 

 high, sharply serrated, complete longitudinal keel. Superior 

 cristae of trunk are continued nearly to the end of the dorsal 

 or not so far. Superior cristae of tail reach nearly to the 

 commencement of the dorsal; the median cristae of the trunk 

 reach as far. Caudal equal to postorbital part of head. Tail 

 somewhat more than twice the length of trunk. Colour diffuse 

 grayish with somewhat light cross-bars on the tail. Snout
