Crangon and Galathea. ]07 



Rostrum shorty deflected ^ clothed above icith a few scattered hairy squaml/'orm 

 tubercles; depressed in median line, terminating in a cylindrical 2mnted tooth, its 

 sides armed with three pointed teeth, and one minute tooth over inner border of or- 

 bit ; first pair of chelipeds hroad, all the articulations very spinous on their borders 

 and superior surfaces ; dactylos short ; propodos clothed with squamiform tuber- 

 cles, scattered among the toothed tubercles ; meros of external maxillipeds longer 

 than ischium. 



The general form of this species is somewhat stunted, the breadth being to 

 the length as 2 : 4. 



The carapace is but slightly longer than broad, and of nearly equal breadth 

 from behind the eyes backwards ; the abdomen of nearly same breadth as the 

 carapace. 



The carapace is depressed above, and armed along its sides and lateral re- 

 gions with spiny teeth. A row of moderately strong teeth marks out the frontal 

 region posteriorly. The rostrum is curved downwards, slightly sulcate in 

 the median line ; it terminates in a short cylindrical pointed tooth ; the lateral 

 margins are produced into three strong teeth on each side, and a smaller one 

 behind over orbit. It surpasses the eye by the entire length of the peduncle. 

 The rostrum and frontal region are sparingly clothed with squamiform tuber- 

 cles, which are oblong and toothed, ciliated with thickset short hairs, and with 

 a number of long hairs scattered among the tubercles, which, in old specimens, 

 give a hirsute appearance to the region. 



The external antenna3 scarcely surpass the entire lengtli of the body. The 

 internal antennas surpass the rostrum by their terminal two joints. 



The first pair of chelipeds are generally as long as the body, closely covered 

 with strong cylindrical, curved, sharp teeth, arranged in rows : these occur on 

 both margins, and on all the articulations. 



The propodos is flattened, moderately broad, and, in addition to the spines, 

 bears above and below a number of dentated, ciliated, squamiform tubercles, 

 which above, in addition, bear scattered long hairs, giving a hirsute appear- 

 ance to the limb. The dactylos is triangular in form, coarsely dentated on its 

 outer edge, and covered with tufts of long hairs. 



The second, third, and fourth pairs of chelipeds are coarsely toothed
