Head Sf in length ; depth 3^ ; D. VIII— 1, 12 ; A. Ill, 13. Lateral line 

 forkiug at base of caudal; thence continued to margin of fin ; 02 tnbeR 

 from shoulder to fork ; 5^ series above lat. 1., 10 below. 



Color verj- light olivaceous, tinged with light yellow ; scales on back, 

 with wide dusky margins formed by dark pnnctulations ; belly white ; 

 tip of snout with numerous coarse black points ; a few of these on max- 

 illary also ; vertical fins yellowish and dusky, with black points ; tip of 

 anterior anal rays white ; ventrals whitish ; the outer rays dusky ; pec- 

 torals almost uniform deep black, the color formed by closely approxi- 

 mated coarse black points ; filaments translucent, slightly dusky. 



It is probable that all species of Polynemus have three anal spines 

 and not two, although this latter number has been assigned to various 

 species by different authors. The first spine is very short, and usually 

 largely enveloi^ed in the scales. Our specimen differs from young spec- 

 imens of P. octonemus Grd. (no adults being known) from the Gulf of 

 Mexico in its shorter pectoral filaments, shorter ventral fins, and in the 

 pectoral fins being black. 



One specimen only was obtained at Charleston, where it is evidently 

 very rare. It was wholly unknown to the fishermen. 



42. EcheneiB uaucrates Linn. — Pilot-fish. 



Of frequent occurrence. The specimen obtained has 22 laminae, the 

 length of disk being 4f in total, and the greatest width between pec- 

 torals one-half length of disk. A specimen from Pensacola has 22 

 laminae in the disk, which is contained 4| times in total, and a third 

 specimen, from Saint John's Ri^ er, has the disk also with 22 laminae, 

 but the length only 4J in total. 



43. Remora squalipeta (Dalcl.) J. & G. 



According to Liitken (Contributions Ichthyographiques V, 5) Echeneis 

 squalipeta Daldorf is based on the young of Echeneis remora Liuue. In 

 case, then, it is considered desirable to give generic rank to Remora^ 

 Daldorf's name will be the oldest available for the species. 



iSTumerous specimens from the vicinity of Charleston are in the Charles- 

 ton Museum. 



44. PMhirichthys lineatus (Menzics) Gill. 



Body with the general form and api)earance of Echeneis naucrates, the 

 head much more narrowed anteriorly, the tip of lower jaw thus form, 

 ing a very narrow, linguiform projection, out of line with the rounded 

 profile of sides of head. Mouth with Made gape, the maxillary about 

 f head (from tip of snout). Teeth comparatively large and few in 

 number, somewhat recurved, not forming a close-set band; those 

 laterally in upper jaw in about 2 distinct series, forming a narrow patch 

 in front; no external series of compressed, close-set teeth as is found in 

 Kemora, and no distinct canines, though the outer series are larger than 

 the inner; teeth in lower jaw similar to those in the upper, arranged in 

 about three series laterally, and forming a narrow wide-set patch in
