West Finmark. Herr Sparre Schneider has found it at 

 Vardo, and A. M. N. at Vadso, both places in East Finmark. 



We have inserted Pontocrates arcticus in order to make the 

 account of the northern species of this genus complete.] 



The genus Kroyera, Bate, 1857, embraced a single species, 

 Kroyera carinata, but that type was referable to the pre- 

 viously described genus Monoculodes of iStimpson. Thus 

 Bate's genus was a synonym ; but in 1858 Bate put another 

 species into his genus Kroyera. viz. K. arenaria ; but there 

 was at that time no redefinition of his genus, and thus 

 Boeck was justified, when he found another species which 

 wa-s congeneric with K. arenaria. in forming a new genus 

 for its reception.

As has been already pointed out in the above paper of 

 1888, the genus Westwoodilla cannot be used, as it was 

 founded on a mistake, the first perseopod having been regarded 

 as the second gnathopod. It is remarkable that this error 

 should have been fallen into a second time when W. liyaliua 

 was described. Bate and Westwood could not recognize 

 their own genus or species, and placed (Ediceros parvimanus 

 in an old genus, into which the two species of Westwoodilla 

 would have also found a place had they not been entirely 

 misunderstood by the authors. But although the generic 

 name Westwoodilla cannot be recognized, it is only just to 

 use one of their specific names, and that of that form which 

 was correctly described appears to be the proper name to 

 retain. 



Bate tells us that the types of both " Westwoodilla cwcula '' 

 and " Westwoodilla Jiyalina " were procured among trawl 

 refuse obtained near the Eddystone Lighthouse. The species 

 was also dredged in 1903 near the Eddystone by A. M. N.
