Amphitepis protecta Kcehler ('04), p. 94, pi. 23, figs. 8, 9. — H. L. Clark 

 ('15), p. 244 



Locality.— Albatross station 5359; Jolo Sea (lat. 8° 12' 45" N., 

 long. 120° 37' 15" E.) ; 4,161 meters (2,275 fathoms) ; January 9, 1909. 



Two specimens (Cat. No. 41013, U.S.N.M.). 



Notes. — The diameter of the disk varies between 6 mm. and 6.5 mm. 

 The arms are preserved for a considerable length; one of them, 

 which is entire, exceeds 45 mm. ; these arms diminish rather rapidly 

 in width, becoming extremely slender in their distal half. 



The two Albatross specimens are a little larger than the type, 

 which was discovered by the /Siboga, in which the diameter of the 

 disk did not exceed 4.5 mm. But they agree very well with my origi- 

 nal description. The upper arm plates show in the middle a small 

 elongated depression ; the under arm plates are separated by a rather 

 broad space. I give here two photographs of the larger of the two 

 individuals. 



The type of Amphilepis protecta was found in the Sunda Archi- 

 pelago at a depth of 1,158 meters (632 fathoms). 



AMPHILEPIS REMITTENS, new species. 



Plate 69, figs. 7, 8. 



Locality. — Albatross station 5637; Bouro Island (south) and 

 vicinity; Amblau Island (N.) bearing 80° E., 38.91 kilometers (21 

 miles) distant (lat. 3° 53' 20" S., long. 126° 48' 00" E.) ; 1,280 meters 

 (700 fathoms) ; December 10, 1909 ; gy. M. 



One specimen (Cat. No. 41112, U.S.N.M.). 



Description. — The specimen is of small size and the diameter of 

 the disk does not exceed 3 mm. The arms, of which four are com- 

 plete, are not 10 mm. in length ; they are relatively rather thick and 

 taper progressively without however becoming very narrow in their 

 distal part. Unfortunately the central portion of the dorsal sur- 

 face of the disk is torn away. 



The disk is rather strongly excavated in the interradial spaces. 

 The plates which remain on the dorsal surface are large, rounded, 

 and scarcely imbricated; they become suddenly very much smaller 

 toward the periphery. The radial shields are large, with the internal 

 border almost straight, the external border very convex, and an acute 

 proximal angle ; the two shields of each pair are in contact for about 

 a third of their length, and they are separated inwardly by an 

 elongated triangular plate. The length of these shields is more than 

 twice their width, and is almost equal to half the radius of the disk.
