21. Kuhlia xenura Jor. & Gilb. 



(Xenichihys xenurua Jortlau & Gilbert, Proc. U. S. Nat. Mus. 1881, 454.) 



435G, (Types of A'emc/if/ii/s xenurus.) Two specimens, in good condition. 



This species should be referred to the genus KuMia Gill {—JlJoronopsis 

 Gill), rather than to Xenichthys. It has no enlarged scale in the ven- 

 tral axil, and it has the naked snout, jaws, and fins, the compressed 

 body, and high dorsal spines of the species of Kulilia. 



An examination of the Museum records shows that these specimens 

 now bear a number originally given to one of the types of " EuscJiistodus 

 concolor,^^ from San Salvador. As the connection of these specimens 

 with the Dow collection rests on the same records, we consider it doubt- 

 ful whether they really came from San Salvador.* Kuhlia xenura appears 

 to be a valid species distinct from K. twniura, but it should be suppressed 

 from the list of species inhabiting the Pacific coast of Central America, 

 until its occurrence there is verified bj" some collector. 



22. Centropomus unionensis Bocourt. 



30991. One fine specnueu, in good condition. 



23. Apogon dovii Giiuther. 



30990. Two specimens, in bad condition. 



24. Polynemus approximans Laj- & Bennett. 

 15129. One specimen, in good condition. 



25. Sciasna oscitans Jor. & Gilb. 



309G7. Three fine specimens, two of them adult. 



26. Sciaena armata (Gill) J. & G. 



{BairdieUa armata Gill, Proc. Ac. Nat. Sci. Phila. 1863, 164 = Cwvina acutirostris 

 Steinflachuer Ichtli. Beitr. Ill, 28, 1875.) 



(Type of BairdieUa armata.) One specimen, in good condition. 



27. Sciaena ophioscion (Gthr.) J. & G. 



{Ophioscion typicus Gill, Proc. Ac. Nat. Sci. Phila. 1863, 165.) 



22861. (Type of Opliio8cion typicus.) One adult si^ecimen, in good 

 condition. 



28. Pomacanthus zonipectus (Gill.) Giintber. 



{Pomacaniliodes zon'ipectns Gill, Proc. Ac. Nat. Sci. Phila. 1862, 244 (adult) = Potiacan- 

 thus crescenialis Jor, & Gilb. Proc. U. S. Nat. Mus. 1881, 358, young.) 



5922. (Type of Fomacanthodes zonipectus.) A large specimen, in good 

 condition, from San Salvador. 



29979. A young specimen (from IsTicaragua), showing the coloration 

 of the '■'•crescentalis'''' stage, which is wholly different from that of the 

 adult. The changes in coloration appear to be analogous to those of 

 Fomaeantlius arcuatus. 



* There is some reason for thinking that these specimens belonged to Dr. Stimpson's 

 olclection, and came from the east coast of Asia.
