216. LORICARIA UCAYALENSIS Regan 
Loricartichthys ucayalensis Regan, 1913, Ann. Mag. Nat. Hist., (8), XII, 281, Rio Ucayali. 
Described from two males, 185 and 220 mm., from an unnamed locality on the 
Ucayali, collected by Mounsey. Near to L. typus in the form of the lower lip, 
and to L. maculata in other respects, differing in the larger head, shorter tail, and 
less elevated dorsal and anal fins. 
217. LoricarIA CASHIBO Higenmann and Allen, sp. nov. 
15416, 1, 131 mm. to end of middle caudal rays, type, Lago Cashiboya, Allen, August, 1920. 
Among the specimens from Lake Cashiboya, one, 131 mm., differs from the 
remainder notably in the length of the snout, and the width of the head, representing 
a new species evidently allied to L. maculata, with which, indeed, it was collected. 
The following comparison is made with a specimen of L. maculata, 188 mm. in 
length to the end of the middle caudal rays:
