three spiniform teeth and reaching nearly to end of antennular peduncle. External maxillipeds con- 

 siderably longer than antennal peduncle. Third pair of legs exceeding external maxillipeds by length 

 of fingers and half the palm. 



Abdomen with a median dorsal carina which terminates on the first segment in an anteriorly directed 

 tooth and on the last segment in a posteriorly directed one; side with shallow sulci, otherwise almost 

 smooth. 



Length of a female, 30 mm. 



Color, yellowish brown, the cephalothorax darker than the abdomen and sometimes bluish or 

 greenish. 



Sicyonia Uevigata is fairly common in Beaufort Harbor, especially on shelly bottoms. 



Sicyonia brevirostris Stimpson. PI. xxv, fig. 4. 



Sicyonia brevirostris Stimpson. 1874, p. 132. 



Integument firm, much sculptured, especially the abdomen; abdomen with scattered tubercles, 

 whole body with a covering of very short and fine setae. Rostrum short, not equaling eyes, its upper 

 margin with three teeth behind the acute tip. Median carina of carapace with three strong teeth. Anten- 

 nal and hepatic spines well developed. Pedxmcle of antennule short, its terminal article a little more 

 than half as long as penultimate. Peduncle of antenna a little shorter than external maxillipeds. 

 Third pair of legs exceeding external maxillipeds by about two-thirds the length of the hand. 



Carina of abdomen prominent, fissured, and deeply notched behind on each segment; first segment 

 with an anteriorly projecting tooth, fifth and sixth segments with backwardly directed ones. Antero- 

 lateral angles of first, second, third, and fourth segments dentiform, those of the third and fourth devel- 

 oped as stout, outwardly projecting, curved spines; posterior lateral angle of fifth segment spiniform. 



Length of a male, tip of rostrum to tip of telson, 78 mm.; carapace, including rostrum, 27 mm.; 

 rostrum, 3.5 mm. 



Three specimens, two males and a female, were dredged by the Fish Hawk in 17 and 63 fathoms 

 outside the harbor. 



Sicyonia dorsalis Kingsley. PI. xxv, fig. 3. 



Sicyonia dorsalis Kingsley, 1878, p. 97; Kathbtm. 1901, p. 103. 



Integument fairly solid, both carapace and abdomen much sculptured. Carapace with a median 

 dorsal carina with one tooth a little behind the middle and one much smaller near base of rostrum. 

 Rostrum uptiuned, its superior margin with three teeth, its tip reaching slightly beyond eyes, notched 

 at end and with small tooth on lower surface. External maxillipeds shorter than antennal peduncle. 

 Peduncle of antennule short, the second article twice the length of third. Third pair of legs reaching 

 slightly beyond external maxillipeds. 



Abdomen with a high median dorsal carina, the anterior and posterior teeth strong; a minute 

 posterior tooth on fifth segment. Sixth segment with a posterolateral spine above which is a triangular 

 tooth. Full-grown individuals with a posterolateral spine on third, fourth, and fifth segments also. 



A single small specimen, 34 mm. long, now in the laboratory collection, was dredged by the Fish 

 Hawk a short distance off the inlet in igoa. Dr. Mary J. Rathbun records an example from Porto 

 Rico 90 mm. long. 

 Sicyonia edwardsii Miers. PI. xxv, fig. 2. 



Palemon carinattis Olivier, 1811, p. 667 (teste Milne-Edwards). 



Sicyonia carinata Milne-Edwards, 1S37, p. 344; ibid., 1834-1840, t. n. p. 410; Dana, 1852, p. 602; Bate, 18S8, p. 294. 



Sicyonia edwardsii Miers, 1881. p. 367. 



Integument, especially of the abdomen, firm. Carapace nearly smooth and ^vith fine scattered 

 hairs; abdomen deeply sculptured and with scattered tubercles. Dorsal carina of carapace with two 

 teeth. Rostrum directed obliquely upward, its upper margin nearly straight and armed with two 

 small teeth; its tip notched and falling short of eyes. Anterior margin of carapace with a small spine 

 below eye. Lateral spines well developed. External maxillipeds reaching terminal article of anten- 

 nulary peduncle and exceeding antennary peduncle. Third pair of legs exceeding external maxillipeds 

 by length of fingers. 



Abdomen with dorsal carina like that of S. brevirostris. Lateral angles of segments not produced 

 into spines. 



The right of this species to be included in the Beaufort fauna rests, so far as is known, on a single 

 specimen of 25 mm. long, dredged by the Fish Hawk in 141 fathoms off Beaufort Inlet.
