FISHES OF THE FAMILY LORICAEIID.E. 285 



teeth on each side. 34-35 scutes in a longitudinal series, 24 + 10-11, the lateral keels 

 weak, obtuse, united posteriorly ; scutes otherwise not distinctly carinate. Lower 

 surface of head naked ; abdomen with 5 or 6 series of plates between the lateral series, 

 the anterior plates smaller and more numerous, extending to the level of the outer 

 angle of the gill-opening; an anal plate bordered anteriorly by several of moderate 

 size. First dorsal ray a little longer than the head ; pectoral spine extending to 

 anterior ^ or middle of ventral ; ventral spine moderately produced, the soft portion 

 of the fin emarginate, the first and third soft rays longest ; caudal emarginate, the 

 outer rays scarcely produced. Breadth of body at level of first anal ray 4 times in the 

 distance from that point to the caudal. Small round blackish spots on head, body, 

 and fins (except the anal), those on the sides of the body larger and forming 1 or 2 

 longitudinal series. 



Total length 270 mm. 



Two specimens (including the type of the species) : E. Amazon. 



19. Loricaria punctata, sp. n. (Plate XVII. fig. 1.) 

 Loricaria laviztscitla (part.) Eigenm. & Eigenm. Occ. Pap. Cal. Ac. i. 1890, p. 380. 



Length of head 4^-4f times in the total length. Breadth of head 1 3-lf times in 

 its length, diameter of eye 0-6 times, interorbital width 6 times, length of snout twice. 

 Snout pointed ; upper surface of head without keels, evenly convex ; supraorbital 

 edges scarcely raised ; orbit with a broad shallow notch ; lips with small papillte, the 

 upper narrow, with tentacular fringes of moderate length ; the lower lip moderately 

 broad, its posterior border smooth, entire or slightly crenulate, emarginate ; free portion 

 of barbel less than diameter of eye ; jaws with about 12 rather small teeth on each 

 side. 30 scutes in a longitudinal series, 19-21 + 9-11, the lateral keels sharp, distinct 

 throughout ; scutes otherwise not carinate. Lower surface of head naked ; abdomen 

 with 3 or 4 series of plates between the posterior plates of the lateral series ; anterior 

 plates smaller and more numerous, extending to the level of the middle of gill-opening ; 

 an anal plate, bordered anteriorly by 4. First dorsal ray as long as the head ; 

 pectoral spine extending to anterior \ of ventral ; ventral spine not produced, the soft 

 portion of the fin emarginate, the fourth soft ray the longest ; caudal emarginate, the 

 outer rays scarcely produced. Breadth of body at level of first anal ray 3f-4^- times 

 in the distance from that point to the caudal. Numerous small dark spots on head, 

 body, and fins (except the anal), those on the sides larger and fewer. 



Total length 180 mm. 



Three specimens: two from Manaos, Bio Negro, Middle Amazon, collected by 

 Mr. J. C. Antony, and one from Porto do Moz, Lower Amazon, received from the 

 Museum of Comparative Zoology, Cambridge, U.S.A.
