15. LoricaRia STRIGILATA. 
Loricaria strigilata Hensel, Arch. Nat. 1868, i. p. 368. 
Closely allied to Z. dima, but with larger eye and more numerous abdominal plates. 
Length of head 4} times in the total length. Breadth of head 11 times in its length, 
diameter of eye 53 times, interorbital width 5 times, length of snout 21 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 43 times in the distance from that point to the caudal. In other 
characters similar to L. lima. 
Total length 105 mm. 
One specimen: Rio 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 43 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 # the length of head; 
pectoral spine extending to anterior 4 of ventral; ventral rays increasing in length 
from the innermost outwards ; (!upper caudal ray elongate). Breadth of body at level 
of first anal ray 43 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.

Loricaria latirostris Bouleng. Ann. Mag. Nat. Hist. (7) v. 1899, p. 165. 
Loricaria paulina Bouleng. t.c. p. 166. 
Length of head 3-4 times in the total length. Head about 13 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 3 the diameter of eye; occipital plate with a pair of weak 
divergent keels; lips papillose, with short marginal fringes; lower lip of moderate
