48. Calamu.s piuniatula. (Gniclieuot, Revision des Pagels, 119.) 

 Martinique; Plee; in poor order, .26"' long. 



As supposed l>y Jordau & Gilbert (Proc. U. S. Nat. Mas., 1884, 20), 

 this is the young of Calamus bajonado. 



49. Calamus microps. (Gniclienot, in Rau)on de la Sagra, Hist. Guitar, 188, tab. 8, 



fig. 1.) ■ 



Specimen in fair condition, .3U'" long, from Cuba; liamon de la 

 Sagra. 



Very close to Cahr.uuu iicnna, ;'r.;m which it may be distinguished by 

 the very small size of liic eye, which is 4i in head. Canines small, 

 irregular, about j| on each side. Preorbital breadth 2:] in head. Max- 

 illary 2i in head. Depth of body 2^ in length. Form of Calamus 



* Hwmulon Mans Haly (Ann. Nat. Hist., Irt75,xv, 268), from Bahia, was overlooked 

 in our review of this geuns. The scanty original description does not distinguish it 

 from H. sciui'us. The following is the original description of Ho'.inulon Mans: 



"D. if. A. f. L. lat. .iO, L. transv. -I\. 



" The height of the body equals the length of the head, and is contained three 

 times and a half in tije total. The snout is of moderate length, rather longer than 

 the eye, which is contained three times and a half in the length of the head. The 

 cleft of the mouth is very wide, the maxillary reaching to the vertical from the center 

 of the eye. Pra?operculum with the posterior limb nearly vertical, obtusely dentic- 

 ulated, the deuticulations somewhat stronger at the angle. Dorsal deeply notched ; 

 the fourth spine longest, nearly half the length of the head, the last spine longer 

 than the eleventh. Caudal forked. Second anal spine stronger but scarcely longer 

 than the third, as long as the sixth dorsal spine. Pectoral one-fifth of the total 

 length. The fish appears to have been longitudinally striped. 



"Two specimens in spirits from Bahia, and a young stuffed specimen from the same 

 locality. The adults are 7| inches long."
