3021. LIOPSETTA PUTNAMI (Gill). 

 (EEL-BACK FLOUNDER.) 



Head 3i; depth 2. D. 55; A. 40; scales 70 (pores). Body oblong, ovate. 

 Eyes rather small, separated by a naked elevated ridge. Jaws sometimes 

 each with 2 distinct rows of teeth, the interrupted outer series of truncate, 

 close set, thickish, incisor-like teeth, which are sometimes movable ; the 

 inner row of similar teeth more widely set and rather distant from the 

 outer row (and often or generally wanting) ; about 20 teeth in outer row 

 in lower jaw; right side of each jaw toothless; iuterorbital ridge contin- 

 uous, with a broad, naked, smoothish, tuberculose ridge, which joins the 

 lateral line. Scales small, distant, nonim.bricate, smooth in the female, 

 and more or less ctenoid in the male, those on blind side smaller. Fins 

 moderate, somewhat scaly; anterior rays of dorsal low; pectoral a little 

 more than -J- head ; bases of vertical fins not tuberculate ; anal spine pres- 

 ent; lower pharyngeals separate, broad, with coarse teeth. Grayish 

 brown, mottled with darker brown ; fins with blackish spots. Length 10 

 inches. Atlantic coast of North America, from Cape Cod northward to 

 Labrador and beyond; occasionally found in abundance. This species is 

 rather common along the coast of northern Massachusetts and northward 

 to Labrador. Specimens are frequently found in the markets, mixed with 

 those of PseudQpleuronectes americanus. The numerous specimens in our 

 possession were found in the markets of Indianapolis, having been sent 

 thither from Boston. The remarkable sexual differences in the species 

 have been fully discussed by Dr. Bean (Proc. U. S. Nat. Mus. 1878, 345), the 

 form formerly called Euchalarodus putnami being the male, and that called 

 Pleuronectes glaber being the female of the same species. These conclu- 

 sions of Dr. Bean are fully corroborated by our series of specimens in 

 which both sexes are fully represented. 



Although Liopsetta putnami is abundant where found, its ascertained 

 range is somewhat limited. The specimens in the United States National 

 Museum represent localities from Salem, Massachusetts, to Belfast, Maine. 

 In the Museum of Comparative Zoology the localities represented are Prov- 

 idence, Boston, Salem, Grand Manan, and Labrador. (Named for Prof. 

 Frederic Ward Putnam. )
