BemarJcs. — M. J. Bonnier has recently proposed to replace this 

 name with Tryphosa because the Orchomenella ciliata of the author has turned 

 Gilt to be identical with Anonyx namus of Kroyer, which was quoted by Boeck 

 in his great work as the type of his genus Tryx)liosa. But the diagnosis origi- 

 nally given by Boeck of the latter genus does not in reality apply to that 

 species, which was not figured in his work, but more properly to the 2 species 

 T. H0rringil and T. nanoi(ki<. Thus he says that the mandibular palp is affixed 

 on the same level as the molar tubercle, which is not the case with the 

 Krayerian species; and moreover the anterior gnathopoda are characterised as 

 elongated, which likewise cannot properly be said of the latter form, but may 

 fairly be so of the other species referred by him to the genus Tryphom. 

 Under such cirumstances, I think 1 am right in retaining- the genus Orcho- 

 menella in the sense originally adopted in this work.

Bemarlis. — M J. Bonnier proposes to separate this species generically 

 from 0. pinyuis on account of the epistomal plate being a little more promi- 

 nent, and on this account to transfer it to the genus Orchomcne. This is un- 

 ([uestionably erroneous, as the present species is otherwise very closely allied 

 to 0. pinguis, and by no means generically distinguishable from it. The 

 latter species M. Bonnier ranges within the genus Tryphosa. 



Distrihution. — Atlantic coast of North America (Sidn. Smith), coas 

 of France (Chevreux).

Occnrrence. — I have found this form of late years in several 

 localities both of the south and west coasts of Norway, as also in the Trond- 

 hjemsfjord. 



Distribution. — British Isles (Robertson).

Remarlis. — I fully admit that this form, as pointed out both by Dr. 

 Hansen and M. Bonnier, is the true Anonyx nanus of Kroyer, and that of 

 course the specific name ciliata ought to be discarded and replaced by that 

 of nana. But as this species does not agree with the diagnosis given by 

 Boeck of his genus Tryphosa, its name must be henceforth Orchomenella nana, 

 and not, as proposed by Boeck and adopted by M. Bonnier, Tryphosa nana. 



Distribution. — British Isles (Robertson), Dutch coast (Hoek).
