The marine fisbes collected by Mr. Gardiner iu bis two expeditions com[)rise examples 

 of 185 species, of wbicli 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 discoA^ered. In addition, there are a number of small " plankton " fisbes, Scopelns, 

 Gonostomu, &c., with some Leptocephali, and also some small specimens dredged in the 

 lagoons of tbe Maldives, which I have not Ijeen 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, Scceopis) 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 liand, some 

 species which were originally described from Japan and which have since been recorded 

 from Indian seas (e. g. Callioni/mus longlccmdatus, Flatycephalus spinosus, Scceops 

 grandisquamis) are now shown not to occur in the Indian Ocean, in which thev are 

 represented by allied, but specifically distinct types. 



Stomiatidse. 



BOROSTOMIAS, gen. nov. 



Differs from Astronesthes, Richards., in having tlie teeth on the maxillary few and 

 wide-set, instead of numerous and in a continuous series. In addition to the new species 

 described below, tliis genus includes Astronesthes richardsoim, Poey, and A. elncens, 

 Brauer.

 diameter of w^hich is 8 in the length of head and 2 in the interorbital width. Mouth 

 very wide, the lower jaw scarcely shorter than the head ; barbel 1^ the length of head.
