 fathoms ; off Tortuga L, Antilles, in 6 fathoms. 



The Bahama Expedition took it at station 3, off Havana, in 

 110 fathoms. The locality of the type was not known. Accord- 

 ing to Bell, it also occurs in Torres Strait. Probably this is an 

 error.

Plate xxviii; figure 3. 



The rays are long, slender, well rounded in life. They are 

 often unequal and vary in number; most frequently they are 

 five or six, sometimes four or seven, due to autotomous division. 

 The dorsal plates in this species are numerous, thick, somewhat 

 convex, irregularly polygonal, and closely crowded, often over- 

 lapping by their edges, mostly without connective ossicles, except 

 very small ones laterally. They are like all the rest of the plates, 

 above and below, thickly covered with fine granules. The pap- 

 ular areas between them are small, with few papulae. 



The marginal plates are rather larger than the dorsals, more 

 quadrangular, and form two nearly equal, regular rows. 



There are usually, in adults, at least two long regular rows 

 and some shorter ones of much smaller, squarish interactinal 

 plates, and also a small triangular interradial group. These are 

 covered and obscured by the crowded granulation. 



Adambulacral plates bear two rows of small, short spinules, 

 and there is also, especially proximally, a row of similar spines
