Figure 41. — Neopontonides beaufortensis (Borradaile). 

 A, anterior part of body in dorsal view, X 19.5; B, an- 

 terior part of body in lateral view, X 13 ; O, antennule, 

 X 26 ; D, antennal scale, X 26 ; E, first leg, X 39 ; F, 

 smaller second leg, X 26; G, larger second leg, X 26; 

 H, fingers of larger second leg, X 65; I, third leg, X 26 

 (after Holthuis, 1951a). 



locerite rather broad, ending in slender point 

 reaching almost to middle of article; outer margin 

 of article slightly concave ending in strong an- 

 terolateral spine reaching end of second article; 

 upper antennular flagellum with rami fused for 

 two to four joints; short ramus with two to four 

 free joints. Antennal scale reaching beyond an- 

 tennular peduncle; concave outer margin ending 

 in strong tooth; lamella exceeding tooth; a small 

 lateral tooth at base; antennal peduncle reaching 

 about to middle of scale. 



First leg reaching beyond end of antennal 

 scale ; fingers slightly shorter than palm, unarmed, 

 slightly agape; carpus about as long as merus. 

 Second legs unequal. Part of palm of larger leg 

 exceeding antennal scale; fingers half or less 

 length of palm, dactyl with two, immovable finger 

 with one tooth on cutting edge; palm slightly 

 swollen ; carpus short, conical ; merus about twice 

 length of carpus. Smaller second leg with fingers 

 as long as palm, slender, unarmed ; carpus nearly 

 as long as palm. Third leg with heavy, simple 

 dactyl. 



Abdomen smooth, all pleura broadly rounded. 

 Sixth segment as long as telson. Telson with two 

 pairs of dorsolateral spines; posterior pair mid- 

 way between anterior pair and tip; three pairs 

 of spines on posterior border, intermediate pair 

 less than twice length of inner pair. Uropods 

 elongate; outer margin of exopod ending in a 

 tooth flanked medially by a movable spine. 



Measurements. — Length of body: male, 9 mm.; 

 ovigerous females, 7 to 9 mm. 



Variations. — In young specimens, the legs are 

 relatively shorter than in adults, and the larger 

 second leg resembles the smaller second leg of 

 adults. 



Color. — Nearly transparent, but with faint col- 

 oration of Leptogorgia from which individuals 

 are taken (yellow or orange). 



Habitat. — This species is found in coastal 

 waters where it lives in association with 

 Leptogorgia; surface to a few fathoms. 



Type locality. — Beaufort, N.C. 



Knoxon range. — Beaufort, N.C, to Grand Isle, 

 La. (Dawson, 1963); Caledonia Bay, Panama; 

 Antigua. 



Remarks. — Ovigerous females have been taken 

 in Bogue Sound near Beaufort Inlet, N.C, in 

 August and November, in Panama in April, and 

 in Antigua in May. 



Subfamily Palaemoninae 



Upper antennular flagellum with both rami 

 fused in basal part. Appendix masculina gen- 

 erally present on second pleopod of male, appen- 

 dix interna on second pleopod of female. Pleuro- 

 branch present on third maxilliped. Posterior 

 margin of telson with two pairs of spines and one 

 or more pairs of setae ( I Iolthuis, 1952).
