distal and the proximal end. The cornea is large and deeply 

 pigmented ; its posterior margin is slightly emarginate above. 

 There are a few small groups of setae on the stalks. The 

 ophthalmic scales are very small, widely separated and blunt. 

 They are hollowed out on the upper surface and bear a spine, 

 which is inserted just below, and slightly to the inside of the 

 tip. The ophthalmic segment is exposed. 



The cornea reaches the middle of the third joint of the an- 

 tennular peduncle when the latter is fully extended. The third 

 joint is considerably longer than either the first or second. The 

 upper flagellum is unusually long and thin ; it is much longer 

 than the third peduncular joint. 



The cornea reaches the middle of the fifth joint of the an- 

 tennal peduncle. The external process of the second joint of 

 the peduncle is massive and pointed ; it bears a few teeth on 

 its upper edge, and reaches to the middle of the fourth joint. 

 The acicle is large and strong, and extends just be3^ond the 

 tip of the fifth joint. There is a small tooth at the inner side 

 of the base of the acicle. The third joint, which is hardly 

 seen from above, has a small sharp tooth at its distal end. The 

 fourth joint is short, thick and practically cylindrical. The 

 fifth joint is more than twice as long as the fourth and is later- 

 ally compressed ; it is slightly dilated towards the distal end. 

 The fiagellum is nearly three times as long as the carapace. 



The right cheliped is much larger and more massive than 

 the left. The merus is laterally compressed and its surface is 

 covered with low broad scales fringed with hairs. The upper 

 and outer surfaces of the carpus are flattened. The inner 

 edge of the upper surface is marked by a row of about twelve 

 or fourteen strong teeth ; on the outer edge of the upper surface 

 there is a similar row but it is composed of smaller teeth. There 

 are many low scales on the flanks of the joint but hardly any 

 on the dorsal surface. The propodite and dactyl form a nar- 

 row oval. The palm is a little shorter than the carpus and 

 considerably longer than the fingers, which end in small yellow 

 claws. A low median ridge, made up of rough tubercles, begins 

 at the proximal end of the propodite but it dies out about half 

 way to the base of the fingers. The outer margin of the hand 

 is well defined and is entire. The inner margin of the palm 

 bears a row of teeth, which decrease in size distally and die 

 out before reaching the base of the dactyl. The margin of the 

 latter is rounded and entire. The upper surface of the hand is 

 smooth and bears only a very sparse sprinkling of hairs. 



The left cheliped is smaller than the right but not so markedly 

 so as in most species o^ Eupagurus. Each joint is narrower than 

 in the right cheliped, otherwise the structure is much the same. 

 The teeth of the carpus and the ridges are more accentuated 

 and the setae more plentiful than on the right. The fingers 

 are equal in length to the palm. Both margins of the hand 

 are entire. The cutting edges of the fingers are furnished 

 with chitinous spines.
