The short rostrum distinguishes this at once from L. 
nasicus and jpallidus ; the absence of the three spines on 
each side of the central line of the middle lacinia from L. 
nasicoides ; and the more numerous teeth of the crest from L. 
fulvus and L. acutirostris.

A 1 Porcupine ’ Eudorella is so near E. hirsuta that I prefer 
provisionally considering it a variety of that species to giving 
it a distinctive name. I give, however, the characters. 
Cephalothorax deepest at the anterior part of the carapace, 
and thence gradually becoming shallower to the last segment, 
which is not deeper than the abdomen. Carapace subequal 
in length to the free segments ; front margin truncate, but 
not retuse, the lower two thirds of this margin and also the 
lateral margin denticulate throughout; denticulations of nearly 
equal size ; infero-antcal angle well rounded off; a narrow 
sulcus at about one-fourth-way up the anterior margin, but 
the denticulations are not interrupted even by this sulcus, but 
pass down into it; there are about six denticulations from the 
bottom of the sulcus to the infero-anteal corner, and about ten
