This species is allied to L. validus, De Haan, but is distinguished 

 from it by its longer rostrum and the form and arrangement of 

 the lateral spines. Its nearest ally, however, is L. long is}) inns, 

 Miers, from which it differs merely in the form of the rostrum. 

 A variety fintegrifronsj with the front almost entire, broad and 

 triangular, of which there are specimens both from Torres Straits 

 and Port Denison, appears to approach very nearly to Mr. Miers' s 

 L. latirostris, if not identical with it.
