occludent side of the summit, which is therefore very obtuse. Carina 

 straight, abruptly bent at the umbo, which is near the apex. Upper 

 lateral plate vertical, long, and narrow. Rostrum small, projecting. 

 Rostral and inframedian latera conic, projecting. Carinal latera 

 long, the upper end projecting. Subcarina long, the apex project- 

 ing. Peduncle somewhat shorter than the capitulum, densely 

 covered with small pebble-hke scales, those near the base elongated. 

 On the carinal side of the peduncle there are two longitudinal series 

 of larger, more projecting scales, and on one side there is another in- 

 distinct series of similar scales. 



Length of capitulum, 12 mm.; basal width, 11; length of peduncle, 

 11. 



This species is somewhat related to S. scorpio Aurivilhus, and espe- 

 cially to S. pollicipedoides Hoek, but differs from both in the pecul- 

 iarly obtuse summit, the rows of enlarged scales of the peduncle, and 

 various other characters. 



VERRUCA ALBATROSSIANA, new species. 



Type-spedmen.— Cat. No. 43472, U.S.N.M. 



Type-locality. — Albatross station 5447, east of Luzon, 310 fathoms. 



A species with the movable valves parallel to the plane of the base, 

 parietal areas of the walls ribbed vertically, basal margin acute, fixed 

 scutum without internal pit or myophore. Movable scutum has five 

 articular ridges counting the crescentic ridge, the rest of the plate 

 being transversely grooved and finely striate longitudinally. Movable 

 tergum having four articular ribs and a stronger diagonal rib. Apices 

 of fixed scutum and tergum contiguous, a little produced. The 

 carina occupies much more of the carino-rostral wall than the rostrum, 

 which is higher and shorter, the apices of both being marginal. 



Carino-rostral length between apices, 5.8 mm.; greatest width, 

 5 mm.; height of fixed tergum, 3.5 mm. 



The unusual length of the rostrum and fixed scutum characterize 

 this species. 



VERRUCA INTEXTA, new species. 



Type-specimen.— C&t. No. 43468, U.S.N.M. 



Type-locality. — Albatross station 5259, off northwestern Panay, 

 312 fathoms. On spines of echinoids with Megalasma. 



The barnacle is white, solid, with the opercular valves about parallel 

 to the plane of the base; parietal areas of the plates of the wall 

 widely ribbed. 



Movable scutum with three articular and three other ribs, the inner 

 face deeply concave ; movable tergum with two articular and a strong 

 diagonal rib, the rest of the plate transversely grooved. Fixed 

 scutum and tergum having rather long, recurved beaks. Carina and 

 rostrum interlocking with numerous teeth, the upper rib and tooth 

 of the carina much longer than the others; beak of carina somewhat
