Decapod Crustacea of Bermuda, Part II. 127 



bidentate; other legs have a row of spines on the propodus and 

 dactyl and are biunguiculate. 



Carapace has a pair of anterior dorsal spines at base of rostrum ; 

 last abdominal segment is much elongated and compressed. Tel- 

 son is tapered, narrow, with four dorsal and four small terminal 

 spines. Uropods have two distal spines at the suture. 



Type-species is T. lanceolatum St., from Hong Kong. In that 

 species the third, fourth, and fifth abdominal segments are cari- 

 nated and have a dorsal spine. 



Stimpson did not mention the presence of a pair of spines near 

 the base of the rostrum, nor the peculiar structure of the third 

 maxillipeds. He merely says they are short. Nor did he mention 

 the bifid character of the ambulatory feet. Therefore our species 

 may not be strictly congeneric with his type. The characters of 

 the rostrum, antennulge, jaws, etc. seem to be the same.

This very slender and transparent shrimp can be recognized 

 easily by its elongated form and very long and slender, tapered, 

 dagger-shaped rostrum, longer than the carapace, thick and 

 rounded and without denticles or spines above, but with many 

 minute sharp serrulations beneath; about 16 or 17 in our examples, 

 largest on the proximal part; with 2 to 5 rough hairs between 

 them. The dorsal margin is nearly straight or a little curved 

 upward distally. 



The margins turn down so as to form a deep channel on the 

 under side, open for more than half the length, and apparently 

 adapted to enclose and protect the antennules. In our examples 

 one margin is narrower than the other and without denticles. The 

 tip is acute. A small acute spine, curved forward, is situated back
