along the inner; those of the last pair are longer than the last ural segment, smooth along 

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

 lanceolate-acute, the exterior ones shorter than the interior. The rami are finely serrated 

 along both margins. 



The telson is tongue-shaped, the margins smooth; it is a little longer than half the 

 length of the peduncle of the last pair of uropoda.

The name in honour of Professor Carl Ci.avjs. 

 PI. VI, fig. 14—23. 



Diagn. Corpus latum, obtuse carinatum. Caput curtum, non rostratun. Oculi parvi, elongati. Seg- 

 mentum primum pereii brevissimum, segmentum tertium et quartum ante vallata, segmenta 

 tria ultima segmento quarto paullo lougiora. Pedes pereii primi paris metacarpo crasso 

 fere conico, paullo longiore quam latiore. Pedes quarti paris pedibus quinti paris lougiores. 

 Pedes sexti paris pedibus quarti paris breviores, quam pereion dimidio breviores. Pedes 

 septimi paris pedibus quinti paris longitudine fere jequales. Segmenta plei non serrata. 

 Pedes uri lati, breves. Telson peduneulo ultimi paris pedum uri brevius, lingulatum. 



The body is broad, obtusely keeled. The head is short, without rostrum. The eyes 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 than 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, which is provided with rounded walls at the anterior margins of most of the seg- 

 ments Probably the male is a little more slender; unfortunately I have seen only the female. 



The body is depressed, marked with an obtuse keel dorsally; this keel is more 

 distinct on the anterior pereional segments and almost evanescent on the pleonal ones.
