 PLOTOSUS Lace'pede. 



113. Plotosus ang-uillaris Bloch. Apoa. Samoa; Waigiu; New Guinea; Solomon Islands (Seale); 



Asia; East Indies. 



Plotosus ikapor Lesson, Voy. Coquille, Zool. II, 132, pi. 31, fig. 3, 1830, Waigiu. 



This little catfish is occasionally taken in shallow water inside the reef at Apia. The yellow 

 stripes on the sides are very faint or wanting in our specimens, which otherwise do not seem to differ 

 at all from specimens from Nagasaki. We therefore place the species of the South Seas (Plotosus 

 ikapor, described first from Waigiu) in the synonymy of Plotosus anguillaris. 



Color dark olive, mottled, white below; sides with scarcely a trace of pale stripes; fins dusky, 

 especially on the edges. Young individuals more distinctly marked, with two white stripes. 



CNIDOGLANIS Gtmther. 



114. Cnidoglanis macrocephalus (Cuvier & Valenciennes). New Guinea (Macleay); Timor.

115. Tachysurus graefn (Kner & Steindachner). 



Arius grxffi Kner ct Steindachner, Sitz. Ak. Wiss. Wien, 1867, 28, Samoa. 

 This species is described from Samoa. Perhaps the specimen is not Samoan, but came from the 

 East Indian region, where catfishes of this type are abundant.
