The other specimens, on the contrary, are not of such evident symmetry, 
the number of processes and pedicels being more variable, and the processes 
being much more flexible, almost like those in Oneirophanta mutabilis. 
With regard to the deposits, all the specimens resemble the last-mentioned 
species, to which they also bear a strong resemblance regarding the shape of 
the genital tubes. According to the shape of the deposits, Deima Blakei has a 
much thinner and more flexible integument than Deima validum. Considering 
the obvious agreement with both Deima and Oneirophanta, I think the Blake 
specimens properly may be regarded as transitional forms combining these two 
genera. In external appearance, in the arrangement of the pedicels and pro- 
cesses, in the shape of the tentacles, etc., they closely remind one of the genus 
Deima. 
Habitat. St. Vincent; depth, 573 fathoms; six specimens. Lat, 17° 28/ 
30” N., Lon. 77° 30’ W. (1880) ; depth, 610 fathoms ; one specimen. 
Orphnurgus asper, THEEL. 
Habitat. Guadeloupe ; depth, 583 fathoms. A single specimen. 
Euphronides depressa, var. minor, n. 
All the specimens are greatly deformed. The largest attains only 150 mm. 
in length. The azygos dorsal appendage is, as a rule, small. 
Habitat. Lat. 39° 38’ 20” N., Lon. 70° 56’ W.; depth, 1241 fathoms ; 
numerous very badly macerated specimens. Lat. 24° 33’ N., Lon. 84° 23/ 
W.; depth 1920 fathoms ; several specimens. Lat. 41° 24’ 45” N., Lon. 
65° 35’ 30” W. (1880) ; depth 1242 fathoms ; one specimen. 
(?) Benthodytes typica, Tuten. 
All the specimens are badly macerated and deformed, and in such a state of 
preservation as to render a closer examination impossible. As a rule, all the 
Psychropotide change very considerably when preserved in alcohol, and, in 
order to understand their organization and external appearance, it is quite 
necessary to see them living. 
Habitat. Martinique ; depth 1030 fathoms ; numerous specimens. Lat. 
24° 33’ N., Lon. 84° 23’ W.; depth 1920 fathoms; numerous specimens. 
Lat. 24° 30’ N., Lon. 88° 58’ W. ; depth 1568 fathoms ; several specimens. 
Lat. 19° 7’ N., Long. 74° 52’ W. ; depth 1200 fathoms; two specimens. , 
Benthodytes assimilis, n. sp. 
The species presents the greatest similarity with Benthodytes sanguino- 
lenta, and differs from it only in some minute features, which possibly may
