one Hydrachnid. The other stomach came from a specimen 180 mm. long and 
held eighteen dipterous larvee and one large Odonate larva. Both specimens 
were from Santarem. 
(4) Sternarchorhynchus oxyrhynchus (Miller and Troschel). 
Head produced into a long, decurved, tubular snout; mouth very small, 
terminal, and inferior; teeth minute in both jaws; size moderately large. The 
table lists the contents of the stomachs of three small specimens.

(5) Sternarchorhamphus miillert (Steindachner). 
Head produced into a long, straight, tubular snout; mouth rather small and 
somewhat inferior; teeth minute in both jaws; size large, reaching 800 mm. in 
length. Two stomachs of this species were examined and the contents are stated 
in the following table:

The food of the last two species, S. oxyrhynchus and S. miilleri, consisted 
almost entirely of mud-inhabiting forms. The Annelida were small mud-worms 
and the dipterous larvee were similar to the North American ‘“ Blood Worm.” 
In addition to the food listed in the foregoing table and that given with the pre- 
ceding species large amounts of mud were found in all stomachs of these species 
which were examined. There is thus a great similarity between the contents of 
the stomach of these two species and of Rhamphichthys rostratus. Not only 
were the same forms eaten by these three species, but they were evidently taken 
in the same manner. The anterior thirds of these three species are similar.» All 
three have the head produced into a long tubular snout. The snout of S. oxy- 
rhynchus is decurved so that the mouth is on a level with the outer edge of the anal 
fin. The snout of Rhamphichthys rostratus is straight but is jomed to the rest 
of the head at an angle to the long axis of the body so that it is directed downward. 
This places the mouth on a level with the origin of the anal fin. The mouth is
