l) The same Museum contains also the following specimens of C. liaspis (Blkr.): 

 one bottle (3855) with the label "-Syngnathus micrognathus s. n. Syngnathus 

 compressus K. & v. H." Java, coll. by KUHL and VAN HASSELT; the other (3854) 

 with the label " Syngnathus micrognathus K. & v, H." coll. by MULLER in Borneo. 

 We presume that KAUP took notice of the first bottle, when he mentioned as 

 synonyms of his Hemithylacus leiaspis Kp. (Cat. Lophobr. fish 1856 p. 6l) ''Syng- 

 nathus micropterus et compressus, Kuhl et v. Hass. MSS." "microplcrus" is 

 certainly a misprint for " micrognathus".
