Squilla nepa was only clearly distinguished from 5. oratoria in 1893. The precise 

 identity of the specimens recorded in the following papers is uncertain : —

In the following papers reference is probably made to the true 5. nepa, but there 

 is a possibility of confusion with 5. holoschista : —

The dorsal surface of the carapace and abdomen is finely rugose ; especially so on 

 the median area of the latter. The carapace measured behind the antero-lateral angles 

 is rather less than half its length, including the rostrum. The median carina of the 

 carapace (fig. 49) is sharp and distinct throughout its course. It is bifurcated in front 

 for half , or rather more than half, its length anterior to the cervical groove, and the small 

 median dorsal pit is enclosed in the base 'of the fork. Behind the cervical groove it is 

 bifurcated for the greater part of its length and projects as a prominent tubercle in 

 the middle of the posterior margin. The intermediate and lateral carinae are distinct. 

 The spines at the antero-lateral angles are very strong and project far beyond the level 

 of the rostral articulation ; the postero-lateral angles are rounded. 



The rostrum is a little broader than long and its upturned lateral margins are rather 

 strongly convergent. Dorsally it sometimes bears an obscure median tubercle and 

 this, in one very large specimen, forms an obsolete median carina. 



1 Lanchester does not seem to have been aware of Bigelow's important paper of 1894.
