Suborder OSTRACODEEMI.t 

 (THE TRUNK FISHES.) 



This group includes those Plectognaths which are without spinous dorsal 

 and which have the body inclosed in a 3-augled, 4-angled, or 5-angled box 

 or carapace, formed by polygonal, bony scutes, firmly joined at their 



.1! T ^f A .S erican 8 P ecies seems to be identical with the East Indian Alutera monoceros. 

 Should differences appear on comparison of specimens, the former should apparently 

 stand as Alutera guntheriana, Poey.
