TuE marine fishes collected by Mr. Gardiner in his two expeditions comprise examples 
of 185 species, of which 51 are new to science and 16 more were previously unrepre- 
sented in the British Museum collection ; some remarkable new generic types have also 
been discovered. In addition, there are a number of small “ plankton ” fishes, Scopelus, 
Gonostoma, &¢., with some Leptocephali, and also some small specimens dredged in the 
lagoons of the Maldives, which I have not been able to determine specifically. 
Several of the new species are inhabitants of the deep sea and the others in great part 
pertain to genera (e. g. Champsodon, Callionymus, Sceops) the species of which have 
been considered to be more variable and more widely distributed than appears to be the 
case on a critical examination. 
Many of the species enumerated are already known to have a wide distribution in the 
tropical Indo-Pacific; the ascertained range of several others has been considerably 
extended by means of the collections here dealt with. On the other hand, some 
species which were originally described from Japan and which have since been recorded 
from Indian seas (e. g. Callionymus longicaudatus, Platycephalus spinosus, Sc@ops 
grandisquamis) are now shown not to occur in the Indian Ocean, in which they are 
represented by allied, but specifically distinct types.

Differs from Astronesthes, Richards., in having the teeth on the maxillary few and 
wide-set, instead of numerous and in a continuous series. In addition to the new species 
described below, this genus includes Astronesthes richardsonii, Poey, and A. elucens,
