The Ehrenbergian species of Loxodes, ZL. rostratum, I have 
not seen, and, so far as I can learn, nothing has been recorded 
_ in reference to its food habits. The superficial resemblances 
between it and Loxodes voram, are sufficient to point out the 
generic position of the latter if not the life haunts of the 
former. Their anatomical differences are, however, more con- 
spicuous than their likenesses. 
Loxodes vorax, n. sp. (fig. 1) has the elongated and flattened 
body characteristic of the genus, the dorsal surface being some- 
what convex, the ventral flattened and finely striated longitu- 
dinally, these delicate furrows bearing the vibratile cilia. The 
sides of the body. With Z. vorax the sub-horizontal arrange- 
ment obtains on the left hand margin where they are usually 
conspicuous, but beginning at the posterior extremity they 
leave the right-hand border by a considerable interval, project- 
ing more and more obliquely upward until they stand almost 
erect, and become visible only on careful focussing. 
The adoral groove is much wider than in the type. The usual 
‘corneous membrane is borne within it, and is continued into 
_ the body to form the tubular pharynx. Its color changes to a 
chestnut-brown with age, as is the case with the lorice of cer- 
tain of the Vaginicoline. For this reason the inference is that
