higher behind, its first ray over front of pupil : anal simihir, but higher 

 than dorsal ; no anal spine; pectoral long and slender, ^ in head ; veu- 

 trals ver3" short, subequal, Uf; caudal double truncate, the middle rays 

 1^ in head; scales moderate, smaller on breast and head, all cycloid; 

 late-al line very nearly straight, a short and shallow curve in front, the 

 depth of which is about one-third its length, and scarcely equal to 

 vertical diameter of eye. 



Color brown, obscurely mottled with darker, the darker spots most 

 distinct on the fins. A round diftuse black blotch as large as eye at 

 beginning of straight part of lateral line, ami another at end of its 

 second thiid; a much smaller spot above lateral line before the pos- 

 terior spot, and another below it, these three forming an equilateral tri- 

 angle with the apex backward; another small black spot above curve 

 of lateral line. 



The single typical system in good condition is 10 inches long, and 

 purports to have been taken at Bahia. It has, however, not the aspecr 

 of a troi)ical species, and possibly it may have come from the coast of 

 Patagonia. 



The genus Verecundum (Latin, rerecundus, modest) is near to Lyopsetfa 

 and E>2)p<>glossoid€s, from both of which it diflers in its smooth scales. 

 The head is smaller than in related gener.a. Verecnndum also shows 

 aftiuities with Lioglossina, Xystreurys, and other genera having a strong 

 arch to the lateral line. Verecundtim, Mippofjlossina, Lioglossina, and 

 Xystreurys mark the transition from the type of Hippoglossoides to that 

 of Faralichthys.

 NOTE ON THE PLEURONECTID^. 



Since the publication of the •' Review of the Flounders and Soles 

 {Pleuronectida') of America and Europe" by Jordan and Goss, a num- 

 ber of important additions have been made to our knowledge of the 

 group. I therefore give here a revised list of the species known from 

 American waters. The sequence and classification ibllows that of the 

 paper above cited, a few changes suggested by Dr. Gill in an excellent 

 review of the same paper being accepted.
