along the inner; those of the last pair are longer than the last nral segment, sniooth along 

 tlie outei' margin, provided with a few hairs at the lower inner corner. The rami are 

 lanceolate-acnte, the exteriör ones shorter than the interiör. The rami are iinely serrated 

 along botli margins. 



The teUon is tongue-shaped, the margins sraooth; it is a little longer than half the 

 length of the peduncle of the last pair of ni'op(jda.

The öodij is broad, obtusely keeled. The head is short, without rostrum. The ei/es are small, 

 elongate. The first pereional segment is the shortest, the third the longest; the third and 



' fourth segments are swollen so as to form a roll at the anterior margin; the last three segments 

 together are longer than the fourth. The first pair of pereiopoda with a thick nearly coni- 

 cal metacarpus, a little longer than broad. The fourth pair are longer than the fifth. 

 The sixth pair are a little shorter than the fourth pair, and not longer than half the pe- 

 reion. The seventh pair are almost as long as the fifth pair. The pleonal segments are 

 not serrated. The uropoda are broad and short. The telson is shorter tlian the peduncle 

 of the last pair of uropoda, tongue-shaped.

Lanceola Clausi, in general habitus, is very unlike its congeners and is at once to 

 be distinguished by the short robust legs and the long body with the very broad depressed 

 pereion, Avhich is provided ^vith rounded walls at the anterior margins of inost of the seg- 

 nuMits Probably the inale is a little more slender; nnfortnnately I liave seen only the female. 



The bodi/ is depressed, marked with an obtu.se keel dorsally; this keel is more 



distinet on the anterior pereional segments and almost evaneseent on the pleonal ones.
