15. LORICARIA STKIG1LATA. 



Loricaria strigilata Hensel, Arch. Nat. 1868, i. p. 368. 



Closely allied to L. lima, but with larger eye and more numerous abdominal plates. 

 Length of head 4^ times in the total length. Breadth of head 1^ times in its length, 

 diameter of eye 5-f times, interorbital width 5 times, length of snout 2^ times. 

 29 scutes in a longitudinal series, 17 + 12. Abdomen with 5 series of plates between 

 the posterior plates of the lateral series ; anterior plates smaller and more numerous ; 

 anal plate bordered anteriorly by 3, these 3 again by more than 5. Breadth of body at 

 level of first anal ray A.\ times in the distance from that point to the caudal. In other 

 characters similar to L. lima. 



Total length 105 mm. 



One specimen : Bio Grande do Sul. 



16. Loricaria microlepidogaster, sp. n. (Plate XV. fig. 4.) 



Length of head 4 times in the total length. Breadth of head 1| times in its length, 

 diameter of eye 6^ times, interorbital width 4f times, length of snout twice. Snout 

 rounded. Head, lips, teeth, &c. as in the preceding species. 29 scutes in a 

 longitudinal series, 18 + 11, all in front of the dorsal weakly carinate, the lateral keels 

 weak, united posteriorly. Lower surface of head naked ; abdomen with numerous 

 plates, in 5 or 6 series between the posterior plates of the lateral series, anteriorly much 

 smaller ; anal plate bordered anteriorly by 5. First dorsal ray -f the length of head ; 

 pectoral spine extending to anterior \ of ventral ; ventral rays increasing in length 

 from the innermost outwards ; (? upper caudal ray elongate). Breadth of body at level 

 of first anal ray 4-^ times in the distance from that point to the caudal. Body with 5 

 or 6 dark cross-bands ; fin-rays with blackish spots ; caudal blackish at its base and in 

 its posterior half. 



Total length 95 mm. 



One specimen, from the Rio Grande do Sul, collected by Dr. von Ihering. 



17. Loricaria latirostris. (Plate XVI. fig. 1.) 



Loricaria latirostris Bouleng. Ann. Mag. Nat. Hist. (7) v. 1899, p. 165. 

 Loricaria paulina Bouleng. t. c. p. 166. 



Length of head 3f— 4 times in the total length. Head about 1-J times as long as 

 broad and twice as long as deep. Diameter of eye 8-10 times in the length of head, 

 interorbital width 5 times, length of snout twice. Sides of the head, in the male, 

 swollen, armed with strongly developed bristles. Supraorbital edges slightly raised ; 

 orbital notch equal to about f the diameter of eye ; occipital plate with a pair of weak 

 divergent keels; lips papillose, with short marginal fringes; lower lip of moderate
