Diego, where no author subsequent to Girard has seen it. It is probably 

 generally diffused along the coast, although less abundant than the corre- 

 sponding species {Cha'todi'pienis faher L.) is in the Atlantic, (sonatus, 

 zoned or banded.) 



Ephippus zonatus, Girard, Pac. R. R. Surv., x, pi. 110, 1858, San Diego. (Coll. A. Cassidj.)

656. PARAPSETTUS, Steindachner. 

 Parapgettus, Steindachner, IchtL. Beit., m, 50, 1875 {panamensis). 



Body short and deep, much compressed, the depth not greater than the 

 length. Scales very small, strongly ctenoid, covering th(^ soft rays of the 

 vertical fins; lateral line evenly arched. Snout short, vertically truncate 

 at tip; mouth small; teeth close set, slender and sharp, in 3 or I rows, the 

 outer slightly larger. Opercles unarmed. Soft dorsal and anal long and 

 high, the tips falcate; spinous dorsal represented by 9 short free spines, 

 scarcely rising above the surface of the scales; anal with 3 very small 

 spines. Pectorals short ; ventrals small, I, 5 ; caudal double concave, the 

 outer lobe pointed, the median lobe rounded. One species. This genus 

 differs from the East Indian Monodactyhis {^^I'settus Cuvier & Valenci- 

 ennes) in having the ventral fins x^erfect and the body not excessively 

 deep. The relations of this genus seem to us evidently with the EpMj)- 

 pidw rather than with the Scombroids, among which Monodactylits has been 

 generally placed. But Capros and Antigonia are not fiir distant from it. 

 (Ttapd, near; Psettns, from ipifrta, a flatfish, turbot.) 



2082, PARAPSETTUS PANAMENSIS, Steindachner. 



Head 3; depth l'. D. IX, 28; A. Ill, 24; P. 18. Form of Chcetodipterus 

 faher; the snout very blunt, the lower jaw included; maxillary reaching 

 middle of eye; eye longer than snout, 4 in head. Last dorsal spine + 

 as long as eye, as long as third anal spine ; longest rays of dorsal and anal 

 as long as head, last ray of dorsal and anal shortest, the posterior part of 

 fin rounded; caudal slightly longer than head; pectoral slightly shorter 

 than head; first soft ray of ventral filiform, twice length of last, 2 in 

 head. Color silvery gray, paler below; base of caudal yellowish, with
