REPORT ON NATIONAL MUSEUM. 235 



cult if not impossible to recognize them in the future. The following 

 species appear to have been erroneously considered as new : 



1. Chimcera abbreviata, Proe. Nat. Mus., 1883, 254, is the young of 



C. plumbed, Gill, which is identical with C. affinis, Capello, de- 

 scribed in 18G8. 



2. Sigmops stigmaticus, Proc. Nat. Mus., 1883, 256, does not repre- 



sent a new genus and species, but is simply a badly preserved 

 example of Gonostoma denudata, (Raf.) Bonap., of which we 

 already had a drawing from a "Fish Hawk" specimen taken 

 October, 1881. 



3. Halosaurus goodei, Proc. Nat. Mus., 1883, 257, is not sufficiently 



distinguished from H. macrochir, Gthr. to receive a new name. 

 Mr. Goode and I observed more variation among the types 

 of the latter species than will be found between the published 

 descriptions of the contrasted forms. 



4. Stephanoberyx monce, Proc. Nat. Mus., 1883, 258, belongs to the 



same genus as Gill's proposed Acanthochcenus, and the fam- 

 ily Acanthochcenidw is unnecessary, as both the species are 

 Berycoids. 

 The remark "closely allied to Melamphaes n was intended to follow 

 and apply to Plectromus. 



5. Typhlopsaras shufeldtii, Gill, Forest and Stream, 1883, is not 



blind and is not a new genus and species, but is identical 

 with Mancalias uranoscopus, (Murray), " The Atlantic," New 

 York, 1878, n, p. G7, Fig. 20. 

 Other species which are especially interesting are the following : 



33296, 33495, 33560. Argyropelecus olfersii, (Cuv.). We had 



previously obtained A. hemigymmis, so that we now possess 



two species of the genus from the Western Atlantic. These 



are the first specimens of olfersii that we have secured. 



33471, 33563. Sternoptyx diaphana, Hermann, not taken before 



except by the " Blake." 

 33510. Bathylagus species. A specimen, No. 31861, of the same 

 species was taken by the " Fish Hawk," October, 1882, haul 

 1,155, in N. latitude 39° 52', W. longitude 70° 30', 554 fath- 

 oms. The genus was described by Dr. Gunther (Ann. and 

 Mag. Nat. Hist, September, 1878, p. 248) from examples ob- 

 tained in the Antarctic and South Atlantic, at depths ranging 

 from 1,950 to 2,040 fathoms. Our species resembles his B. 

 Atlanticus very closely, but has a longer anal.

Accession ; catalogue, 32049-32661, 32665-32682, 32684- 



32688. A valuable collection, especially for geographical distribu- 

 tion, and because of numerous rare species. I name the following : 

 Nemichthys scolopaceus, very fine examples; Coryphcenoides rtipestris ; 

 Melanostigma gelatinosum ; Sternoptyx diaphana; Chaitliodus sloanii?
