NO. 3536 DECAPOD CRUSTACEANS — CHACE 635 



Remarks: This immature specimen differs from Miers' description 

 of D. imperator in a few characters. The frontal margin is deeply 

 sinuous, rather than "nearly straight," and it is armed with, a slender 

 spine directed anterolaterally just lateral to the base of each eye- 

 stalk. The ocular scales each terminate in two divergent spines (the 

 outer one sHghtly stouter than the inner) rather than being "dentic- 

 ulated on theu" outer margins." Also, there are no calcareous plates 

 on the anterior abdominal somites. These differences may be merely 

 characteristic of subadult indi^^duals. 



Distribution: Known only from St. Helena, to a depth of at least 

 25 meters.

 Albunea carabus. — ]\Ionod, 1956, p. 40, figs. 10-14. 



Material: None. 



Remarks: There is nothing in Stebbing's remarks about the speci- 

 men collected by the Scotia at "James Bay, St. Helena, June 2, 1904; 

 Station 499" to suggest that it is other than A. carabus, but reexamina- 

 tion of the specimen would be desirable because of the information 

 that has been gained about the species of Albunea during the past 

 50 years. 



Distribution: Mediterranean; West Africa as far south as Ghana; 

 St. Helena. Sublittoral.
