' I Lave here dismembered the unnatural group of Icosfeidw as given in the Syuop- 

 818, referring Icosteus and Icichthys, in accordance with the views of Dr. Steindaohner 

 (Ichth. Beitr.,XI, 4, 1H81, and XII, 22, 1882), to the Scombroid series, in the neighbor- 

 hood of the liramidce. Steindachner considers Schednphilns the nearest ally of Jconleus 

 ( = Schedophilopsiii spinoaus Steindachner 1. c), and this may be correct. 



The genus Baihi/master is perhaps the type of a separate family, allied to Mulacan- 

 thu8, Latilus, &c., or perhaps to Opisthofinathus. For the present, I unite the Lotilidw 

 with the Malacantkidxe, leaving Bathymaster in a group by itself. This arrangement 

 is, however, merely provisional, until the anatomy of tlie different forme is made 

 known. 



"^ Caulolatilus micropa Goode & Bean. 



The identity of our Atlantic sjiecies of Cavlolatihia with either the Cnban cyanopa 

 or the Brazilian chrysops is as yet unproven, though not improbable. The scales in 

 our species are smaller than they are said to be in the others. There is little differ- 

 ence between C. microps and C. princeps excejjt in color. The scales of the body have 

 each a small brownish spot at base in C. microps.

* Eleolris smaraydus Ctiv. & Val. Esmeralda ncgra. 



Dusky olive, the fins mostly bluish, the dorsal with brown lines; some dark mark- 

 ings about eye, and on base of pectoral above. Body very long and slender, com- 

 pressed behind, the form much as in Goiionellns oceanicus. Head depressed, flatfish 

 above, the eyes mostly superior, not half the width of the interorbital area, which 

 has a knob near its middle. Mouth very oblique, the lower jaw much projecting,
