DE. H. J. HANSEN ON BATHTNOMUS GiaANTEUS. 19 



My reason for proposing to establish Anuropus, Bedd., as 

 the type of a new subfamily, Amcropince, is that the differences 

 hetween its onoutli-parts and tliose of the Cirolaninoe are so pro- 

 nounced, that it may be considered a practical arrangement to 

 remove Anuropus from the last-named subfamily, which will now 

 be a mucb more uniform and more sharply-defined group. But 

 it is possible that in the future some form may be discovered 

 which will prove to be a transition between Tlurydice and 

 Anuropus ; and after such a discovery the subfamily Anuropince 

 ought to be withdrawn. It is scarcely necessary to compile from 

 the description of the mouth-parts a conspectus similar to that 

 of the OirolanincB on pp. 310-311 of my earlier paper ; when in 

 the future many new forms of the various subfamilies have been 

 studied, at least a few alterations in some of my earlier diagnoses 

 of the subfamilies will most probably be necessary, and every 

 student of the family can then easily compile a diagnosis of the 

 Anuropince from my description and the drawings. 



II. Bathtnomtjs giganteus, a. Milne- Edivards. 



In July this year (1902) Professor E. L. Bouvier published a 

 very valuable and splendidly illustrated work : " Les Bathy- 

 noraes," par Alphonse Milne-Edwards et E. L. Bouvier (Eeports 

 on the Eesults of Dredging under the supervision of Alexander 

 Agassiz, by the U.S. Coast Survey Steamer ' Blake ' : Memoirs 

 Mus. Comp. Zool. at Harvard College, vol. xxvii. no. 2, pp. 128- 

 175, pis. 1-8). Bouvier states in a footnote that he had found 

 an earlier sketch (consisting of three large drawings) treating of 

 Bath, giganteus among the papers of the late Prof. Alph. Milne- 

 Edwards ; but it is evident that at least the main part of the work 

 has been done by himself. He has produced a very detailed 

 report on the external structure of one American specimen of 

 Bath, giganteus, A. M.-Edw., and of the two hitherto known 

 specimens of B. Doderleini, Ortm., and he discusses very 

 thoroughly the systematic position of this exceedingly interesting 

 genus. The Zoological Museum in Copenhagen has obtained by 

 exchange one specimen of B. giganteus from the Museum in 

 Calcutta ; it was captured in the Bay of Bengal, " of£ Groa coast, 

 740 fathoms." Working on Anuropus, I thought it practical 

 besides to look at the external structure of our specimen of
