202 BULLETIN OF THE 



Glyphocrangon spinulosa, sp. nov. 



Rostrum long, acute, margins armed with vertically flattened spinous teeth 

 from base to the level of the anterior extremity of the eyes, beyond which 

 point the margins are unarmed ; the anterior pair of the lateral spines are the 

 largest. A median longitudinal row of smaller spines extends from the ante- 

 rior boundary of the gastric area to the anterior fourth of the rostrum ; anteri- 

 orly, these spines are confluent at their bases, forming a carina which is con- 

 tinued forward beyond the spines to the tip of the rostrum. Just inside the 

 marginal spines is an irregular longitudinal row of very small spinules on each 

 side of the rostrum. 



The carapace is thickly covered with spinules which are laterally compressed. 

 Along six longitudinal lines on each side of the carapace the spines are larger, 

 more flattened, forming interrupted carinae. The third carina (reckoning from 

 the dorsal line) ends anteriorly at the deep branchio-hepatic sulcus. The 

 fourth carina is especially prominent on the hepatic region, where it is broken 

 up into two or three prominent teeth. The two lowermost carinse are obso- 

 lescent. The anterior margin of the carapace is produced into a large external 

 orbital spine, directed obliquely upward and outward. The hind margin of 

 this spine is furnished with a variable number of spinules. 



The abdomen, like the carapace, is spinulose on the dorsum and pleurse. 

 An interrupted carina extends the length of the median dorsal line. On the 

 sixth segment this carina is toothed along its edge. The second to the fourth 

 abdominal pleurse are armed with two spines curved outward and backward, 

 the anterior one being the larger. The fifth pleura is likewise armed with 

 two spines, but in this case the posterior spine is the larger. The sixth 

 pleura ends posteriorly in a single spine directed outward at a greater angle 

 than those of the more anterior somites. The median dorsal abdominal carina 

 is continued along the basal part of the telson as a line of four or five teeth, 

 which decrease in size from before backward.

Glyphocrangon sicarius, sp. nov. 



Rostrum as long as the rest of the carapace, armed with a pair of short, 

 blunt, lateral teeth, a little in advance of the front of the eyes, and with an- 

 other pair of obsolescent ones at the root. Between these two pairs of teeth 

 the margins of the rostrum are concave and slightly raised. From the anterior
