148 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. 48. 



and outside this there is a much smaller and shallower pit. Edge of 

 front bilobed. Upper surface of eve flat, smooth, hemispherical; 

 cornea black, terminal. 



Sides of buccal cavity parallel; anterior edge arcuate. Maxillipeds 

 filling the cavity, merus with antero-external angle slightly produced. 

 Pterygostomian regions protuberant. 



Chelipeds equal in the female; they are granulous toward the 

 margins and smooth in the middle; lower margin of propodus acute, 

 not deflexed; fingers meeting when closed, except for a very small 

 gape at base; teeth of the immovable finger larger than those of the 

 dactylus, the highest tooth being the third from the base. 



The only legs preserved are those of the last pan and a single unat- 

 tached one; they are smooth and fringed with long hair. 



This species is larger than T. nudus Stimpson. 1 viUosus Stimpson 1 

 and rubidus Alcock: 2 the first two have two or more lateral teeth 

 instead of one, while T. rubidus has none. 



HEPHTHOPELTA APTA, new species. 



Type-locality. — Between Cebu and Bohol: Lauis Point Light, 

 X. 27° E., 17.8 miles; lat. 9° 58' 30" X.; long. 123° 46' E.; 175 

 fathoms; gn. m.; temperature 54.5° F.; March 25, 1909; station 

 5419, Albatross; one male. 



Type.— Cat. Xo. 46389, U.S.X.M. 



Dimensions. — Type male, length of carapace, 8 mm.; width, 9.7 

 mm.; width across front and orbits, 4.5 mm.; length of third leg, 

 17.2 mm. 



Carapace granulous and pubescent, with somewhat longer hairs 

 on the lateral margins, edge of front not visible in dorsal view. Eye- 

 stalks moderately constricted next the cornea; although the smooth 

 corneal surface is large, the pigment spot is small and dull-colored. 

 The basal joint of the antennules fills the fossette but is not bulging. 

 The maxillipeds gape considerably, and when in place the palpus 

 does not cover the orifice of the efferent branchial canal; the merus 

 has its rounded outer angle produced a little. 



The chelipeds are rather massive and very unequal; margins of 

 merus granulous, a few granuliform denticles projecting from the 

 lower margin; a tooth at inner angle of carpus. Larger chela 

 smooth except on the margins; palm high and thick; fingers meet- 

 ing in their distal third: the immovable finger is bent down at its 

 extremity, its upper edge along the gape is bent strongly outward 

 and forms a tooth distal to the middle; near the base of the concave 

 prehensile surface there is a tubercle; dactylus arched, having a 

 large tooth near its middle. Smaller chela thick, lower surface
