Scales of the Brotulid Fishes. 323 
at right angles to the latero-basal, or rarely continuous with 
a latero-basal, making a large L; lateral system of radii 
continued across the apical field, so that there are radii all 
around ; fine lines between circuli in apical field usually 
well developed, though they may be absent when the nucleus 
is far apicad. 
Monomeropus garmani, Smith & Radcliffe. Type. Celebes 
(U.S.N.M.). 
Scales nearly 4mm. long and slightly over 2 broad, rather 
parallel-sided and truncate at ends; nucleus considerably 
above the middle; about 15 basal radii, few reaching 
nucleus; lateral and apical radi very feebly developed ; 
apical field with the lines or network between the circuli 
very well developed. ‘These scales are quite of the same 
general type as those of Monomitopus. Monomeropus 1s, 
perhaps, not more than a subgenus. 
Barathrodemus nasutus, Smith & Radcliffe. Type. Celebes 
(U.S.N.M.). 
Seales broad-oval, rather over 2 mm. long and 1°5 wide ; 
numerous radii all arcund ; nucleus basad of middle. This 
differs greatly from the Monomitopus group by the position 
of the nucleus and wide spread of the basal radii. 
Glyptophidium lucidum, Smith & Radcliffe. Type. Be- 
tween Gillolo and Kayoa Is. (U.S.N.M.). 
Dorsal scales about 4°5 mm. long and 3°75 broad. The 
only one I obtained is latinucleate, but it shows rather 
widely spaced radii all around. I cannot distinguish it 
from the scales of G. oceanium, although the two fishes seem 
to be subgenerically distinct.

GUS INE.) 
I took a loose scale from the dorsal surface of the type, 
but on examination it proved to be that of some Macrurid. 
Dr. H. M. Smith kindly sent me several lots of scales subse- 
quently, clearly establishing their character. The scales are 
rather large, more or less quadrate, but very variable in 
shape, with the nucleus about the middle or nearer the base. 
There are linear radii all around, and the lateral ones tend 
to be strongly curved basally, so that they diverge nearly at
