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 carino. 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 carine 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 pleuree. 
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 pleure 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 ata 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 cf 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
