The separate tooth on the carina of the carapace is followed 

 by eight teeth on the rostrum, which has no ventral teeth and 

 reaches about to the end of the peduncle of the first antennae, 

 this being level with the tooth of the scale of the second 

 antennae. In the first antennae the second joint is stout and 

 long ; the flagellum of the second pair is much longer than 

 the body. The telson is dorsally sulcate, sharp-pointed, with 

 lateral setae but not spines. The length of the single dry and 

 brittle specimen is about 52 mm. The place of origin is 

 uncertain, and perhaps the same epithet should be applied to 

 the identification, as thorough examination was not feasible.

PENAEOPSIS SPINULICAUDA, n. sp. 

 Plate LXVIII. 



The characters which induce me to name this species as new are 

 to be found in the lanceolate telson which has no large or projecting 

 lateral spines or processes, but numerous little spines within the 

 margins and some that are dorsal among a large number of spicules ; 

 further, in the second maxillae, of which the endopod has at the apex 

 two notable spines on one surface and one on the other, and seven 

 or eight little teeth along the inner margin; and further in the 

 symmetrical petasmata, which are fringed along the adjoining 

 margins with innumerable microscopic hooks, and at the two 

 extremities appear to differ somewhat from these organs so far as 

 known in other species. 



The rostrum has no ventral teeth but eight dorsal, the last of 

 which is behind the orbit and is followed at a distance by a small 

 tooth on the long carina of the carapace. The eyes are very dark, 

 bean-shaped. In the first antennae the second joint is more than 

 half as long as the first and more than twice as long as the third ; 

 the flagella are a little shorter than the first two joints of the 

 peduncle combined, one flagellum for two-thirds of its length much 

 stouter than the other. The scale of the second antennae reaches 

 the end of the peduncle of the first ; the flagellum is 96 mm. long. 



The mandibles have the molar broad, the second joint of the palp 

 very large and setose, distally narrowed. Lower lip with a small 

 group of setules at the inner corner of the broad lobes. The first
