Descriptions of twenty-five new species of fish from the southern United States, and three new genera, Letharcus, Ioglossus, and Chriodorus

412 PROCEEDINGS OF UNITED STATES NATIONAL MUSEUM. Color in spirits uniform olivaceous, the scales dark-edged ; lips and some of membrane bones of head margined with blackish. Fins dusky; each 7th (to 10th) ray of vertical fins with a very small but conspicu-ous black spot on its middle. A single specimen (31099, U. S. Nat. Mus.) was collected at Santa Barbara, California, by Mr. A. Larco. In the collection of which these specimens formed a part, are the fol. lowing species not hitherto known from farther south than Monterey: Oxylehius pictus^ Oplildium taylori, Anarrhichthys ocellatus, as also a sin-gle specimen of Siphostoma hairdianum. United States National Museum, July 11, 1882. ©ESC'RIPTIONS OF T^^ENT V-FIVE ^EW SPEC'DES OF FISH FRO:^: THE SOITTHER.'V UIVITED STATES, A.N» THREE NEW GENERA, I.E. THARCUS, lOGLOSSUS, ANO CHRIODORIJS. By G. BRO^V]\ OOODE aawl TARL.ET©]V M. IRE AN. The following budget of descriptions is presented as the result of a partial examination of the large collections of fishes from the Southern Atlantic States in the United States National Museum, some of which have been on hand for twenty years or more. 1. Tetrodon nephelus, n. sp. The types are numbered 31427, 31428, and 2G570. The first two were taken at Indian Eiver, Florida, by Mr. E. E. Earll; the last at Pensacola, Florida, by Mr. Silas Stearns. The specimens range from 7i to 9 inches in length. This species is the southern representative of Tetrodon turgidus, from which it differs in several particulars, as mentioned below. Tlie spines of the upper parts are much larger, farther apart, dis-tinctly stellate with conspicuous roots; they extend backward not quite to front of dorsal above and to the vent below, the whole region behind these points being entirely smooth. There are less than 40 spines on the median line of the back between the eye and front of dorsal. The dorsal is larger than in T. turyidus, its base one-fifth to one-sixth as long as the head, its largest ray three-sevenths as long as head. The anal, also, is larger than in turgidus, its longest ray nearly one third as long as head. The humeral process is somewhat longer than in tKrgidus, its length from axil of pectoral being a little more than half that of head. Head contained 2| times, dei)th 4 times in length to caudal base. D. 8; A. G (D. 7; A. 5 in T. targidus). Color somewhat variable, but distinguished from that of turgidus by the i)resence of paler blotches on the back and sides, around which the ground color often forms distinct reticulations. Dark bars on the sides
