caudal base. Caudal rounded convex!}'- behind. Pectoral large, very- 

 broad, extends back but little short of anal, and large thickened 

 lower rays nearly forward to hind preopercle edge. Ventral origin 

 nearly opposite second dorsal spine base. Fin about I to anal, and 

 spine nearly f of fin. Vent before anal space equal to orbital socket. 



Color in alcohol rich brownish generally, variegated with darker 

 to blackish or dusky-brown, or whitish, fading quite pale and ^\"ith 

 very obscure mottlings on belly and under surface. Head similar, 

 only lov/er surface more mottled or streaked with whitish. Preor- 

 bital region and cheek below with more or less blackish. Fins all 

 brownish, variegated with handsome waved darker bands or streaks. 

 Uppermost portion of each membrane of spinous dorsal dusky, three 

 large dark crossbands on caudal, and about same on pectoral. 

 Ventral and anal paler than dorsal, former more so on inner surface 

 and outer with few obscure or pale brown spots. Iris pale brown, 

 speckled or blotched with darker, and upper half of eye like wrinkled 

 cutaneous curtain. 



Length, 295 mm. Cat. No. 42175, U.S.N.M. 



The fine example described above agrees quite closelj- with Stein- 

 dachner's figures, though they do not show the large blackish blotch 

 below the suborbital stay and another smaller one in the axil just 

 above pectoral base. 



The present species is apparently allied with Scorpaena ustulata 

 Lowe, of which I have no examples for comparison. However, 

 Bellotti's figure ^ agrees with an Italian example of Scorpaena scrqfa 

 Linnaeus in the apparently less developed armature of the head, 

 weaker dorsal and anal spines, maxillary extending slightly behind 

 eye edge, and soft dorsal with 10 branched rays. Bellotti also shows 

 an antero-orbital tentacle above and another larger, broader one 

 at same point but still higher, and a dark submarginal blotch between 

 eighth to tenth dorsal spines. In the Italian example noted, which 

 is about the same size as S. senegalensis, the latter has a larger and 

 prominent antero-orbital spine, eye H in snout compared with If 

 and the scales very different. In the Italian example the scales are 

 rather less rounded in general contour, and the basal striae much 

 fewer and confined within the limits of the corners of each scale, 

 not spread out like a well-opened fan. Collett figures an example of 

 S. ustulata ^ which differs in many ways, a few of which are its 

 lack of tentacles or skinny flaps, very different armature, indication 

 of scales on head only on postocular and below hind part of subor- 

 bital stay, hind caudal edge but little convex, greatly longer first 

 anal spine, no preorbital pit, coloration, etc. Compared with Scor- 

 paena plumieri Bloch, represented by two examples from Santo
