KEY TO THE GENERA OF THE BEAUFORT REGION. 



o. Rostrum rather broad, its margias toothed Galaihea. 



aa. Rostrum slender, tootliless except at extreme base Munida. 



Genus GALATHEA Weber. 



GalaUua Weber, 1795, p. 94. 

 Galathea rostrata H. Milne-Edwards. PI. xxix, fig. 4. 



Galalhta roslrala H. MUne-Edwards, 18S0, p. 47. H. Milne-Edwards and Bouvier, 1894, p. ^s'l ibid., 1897. p. 14; Benedict, 

 1903, p. 303. 



Carapace somewhat flattened, crossed by numerous strong, ciliated ridges, its lateral margins with 

 a number of acute spines and its front prolonged into a broad rostrum which is acute at tlie tip and has 

 four strong, anteriorly projecting spines on each side. Abdomen with cross ridges like those on the cara- 

 pace but without spines. Chelipeds nearly twice as long as the body, comparatively heavy, with 

 rows of spines or spiniform granules along the margins and appressed, squamiform, ciliated granules 

 on the surfaces; a few larger spines on the carpus and the distal end of the meros; hand a little shorter 

 than the body, fingers gaping widely at the base. 



Length, carapace 9 mm.; cheliped, 20 mm.; hand, 10 mm. 



A single, much mutilated specimen of this species was obtained, in 1915, by the Fish Hawk on 

 the fishing grounds in 14 fathoms. Other specimens, probably from about the same locality, were 

 obtained during the dredging carried on in 1902. 



Genus MUNIDA Leach. 



Munula Leach, iSao, p. 52. 



KEY TO THE SPECIES OF THE BEAUFORT REGION. 



a. Abdomen unarmed with spines irrasa. 



aa. Second, third, and fourth abdominal segments with four spines each longipes- 



Mimida irrasa H. Milne-Edwards. PI. xxvm, fig. 8. 



Munida irrasa H. Milne-Edwards, 1S80, p. 49; Benedict, 1903. p. 310. 

 Munida caribtra H. Milne-Edwards and Bouvier, 1S97, p. 25. 



Carapace spiny in anterior half and adorned with iridescent pubescence. Median rostral spine 

 about twice and lateral rostral spines about half as long as eye. Lateral border with seven spines. 

 No spines on abdomen. Meros of third maxilliped with three spines on the lower margin. Chelipeds 

 three or four times as long as carapace, the meros with rows of spines which are continued onto the 

 carpus and hand. Second pair of legs reaching the proximal end of the hand. 



Length of body of a male, 35 mm.; of carapace, 19 mm.; of cheliped, 66 mm.; width of carapace, 

 II mm. 



Several specimens were obtained by the Fish Hawk in 1902 at a depth of 66 fathoms and again in 

 1914 at a depth of 47 fathoms (station D8249), about 23 miles off Cape Lookout. 



Munida longipes H. Milne-Edwards. PI. xxvin, fig. 9. 



Munida longipes H. Milne-Edwards, 1880, p. 5°: H. Milne-Edwards and Bouvier, 1897. P- 44- 



Carapace somewhat flattened; front armed with three spines, the two lateral extending a little 

 farther than and tlie median not quite as far as the eye. There are two gastric spines, placed behind 

 the lateral spines of tlie front; a small spine about midway between the gastric spine and the lateral 

 border; about six spines on the lateral border, the first the largest; a longitudinal row of three placed 

 to each side of the cardiac region; and two spines on the posterior border. Second, third, and fourth 

 segments of abdomen ivith four spines each. Eyes large and kidney shaped, their peduncles short. 

 The three anterior pairs of legs more than three times as long as the carapace and armed with many 

 spines. 



Length of body, 47 mm.; of carapace, 21 mm.; of chelipeds, 72 mm.; of third pair of legs, 78 mm.; 

 width of carapace, 16 mm. 



Several specimens were obtained by the Fish Hawk in 1902 at a depth of 172 fathoms (station 7315).
