Dana {loc. cit., pp. 637, 1610) adopts Nocticula, Thompson, 

 Zoological Eesearches, p. 52, pi. 5, fig. 1, as taking prece- 

 dence of Thijsa,nop)oda, but Thompson's genus, while 

 possibly an error for Noctiluca, is too vague for adoption, 

 since Sars [loc. cit., p. 71) identifies it with Euphausia 

 instead of Thysanopioda. Milne-Edwards, among various 

 references to Thompson's Eesearches, leaves his Nocticida 

 unnoticed,

No. 145, sent by Dr. Gilchrist, procured by shrimp trawl, 

 Sandy Point (approx.) N.W. by W. 17 miles, from 914 m. 

 depth. The specimen fully agrees with Hansen's account of 

 the frontal plate and the other characters of the carapace, 

 including the minute denticle a little before the hinder end of 

 the lower margin. Its length is not less than the 32 mm. 

 assigned to the specimen noticed by Ortmann in 1905, and, as 

 in that, the preanal spine has two points, one shorter than 

 the other.
