the Arabian Sea : it is a generalized form, linking 

 together several other genera that have usually been 

 regarded as widely separated. It has a scaly body, a 

 formidable dentition, and eyes with a strong upward 

 cast, but it has no phosphorescent organs. 



Genus 2. Saurus : a shore genus, ranging, in tropical 

 and subtropical latitudes, from the West Indies, across 

 the Atlantic, to the Mediterranean, and across the Indian 

 and Pacific Oceans. It has a scaly body, lateral eyes, 

 no barbed teeth, and no phosphorescent organs. 



Genus 3. Saurida : only differs from Saurus in some 

 particulars of dentition : it does not occur in the Mediter- 

 ranean. 



Genus 4>. Harpodon : is singular in having a three- 

 lobed tail : it has formidable barbed teeth. The 

 " Bombay duck" belongs to this genus, which includes 

 only three species. The body may be completely or 

 only partly scaly. 



Genus 5. Chlorophthalmus : a deep-sea genus, with a 

 distribution similar to that of Saurus. It has enormous 

 eyes and tiny incipient phosphorescent organs, and its 

 scales are well developed. 



Genus 6. Bathypterois : a scaly deep-sea genus of the 

 Atlantic, Indian, and Western and Southern Pacific 

 Oceans. It has very small, almost rudimentary, eyes 

 but in compensation for this, some of the fin-rays are 

 wonderfully prolonged and strengthened to form organs 

 of touch. 



Genus 7. Scope lus : a large and very widely ranging 

 oceanic genus, with a scaly body and with definitely- 

 arranged phosphorescent spots. Most of the species 

 are quite small. 



Genus 8. Neoscopelus, differs from Scopelus only in 

 having a flat snout and a smaller mouth, and in the
