P. 12; A. 215 fays. This species inhahits Lower Essequibo in British Guiana. Speci- mens have been sent to the Berlin and Paris Museums bj the Brothers Schomburgk. Genus 2. RHAMPHICHTHYS, Milll d- Trosch. Diagn. A small mouth, wholly destitute of teeth. Descr. Snout more or less tubularly prolonged, with small, pore- like nostrils, without tubes. Head and body laterally compressed, and covei'ed, with the exception of the head, by small scales. A part of the tail remains free beyond the long anal fin. One perceives sometimes at the point of a damaged tail a pro- jecting cuticular process, destitute of verlebrine, which resembles the reproduced tail of a lizard. Judging from the narrowness of their toothless mouth, these fish must subsist on small insects, and be themselves desti'oyed or injured by predacious fishes, whence it hap- pens that the point of their tail is often defective. I divide this numerous genus into two sections :— a. Species having shorter snouts, icith the anal papilla much developed, the anus situated on the posterior third 2^aft of the head, and the anal Jin commencing under the jwint of the pectoral. Of this section three sj^ecies only are known to me.' 5. Rhamphicthys Artedi, fig. 3. Scha, iii. t. 32, No. 2. Fis. Biagn. The free part of the tail forms between the fifth and the part of the total length, and the thickness of the body scarcely exceeds half its height. Descr. It is a shorter and more compactly made species than the following one, has a somewhat longer head, the eyes situated higher up, and the muciferous pores more conspicuous on the snout, round the eyes, and on the cheeks. Lateral line whitish, and formed of a chain of shorty tubular mucoducts directed downwards and obliquely. Please note that these images are extracted from sca
