70 THE VOYAGE OF H.M.S. CHALLENGER. 



I have not seen this species, though Dr. C. A. Dohrn kindly looked for the type in the 

 collection of his son, Dr. Anton Dohrn (the well-known director of the zoological station 

 at Naples), with a view of sending it to me. From the description it appears to belong to 

 this genus, and to be closely allied to Halohatodes comjxir, from which the different colour 

 of the under side of the bodv distinscuishes it. 



The following description is compiled from the original description, which will be 

 found in the introductory part of this paper. 



Opaque black above, with the following yellowish testaceous markings :— The head (ex- 

 cept a large black central spot, and three smaller ones in front which are black). Thorax : 

 in front two semicircular spots ; behind, in the middle two parallel longitudinal spots, one 

 on each side, shaped like a comma, another on each side transverse and semicircular, a 

 third smaller spot on each side at the apex of the disk ; more posteriorly one transverse, 

 two longitudinal and three smaller apical spots. Front coxse except a black spot above, 

 and femora except three more or less broad l)lack lines. Sides and body below yellow 

 testaceous, the sides with longitudinal black streaks. Antennae, middle and hind legs, 

 and front tibife blackish. Eostrum yellowish testaceous, apex black. Eyes fuscous 

 fulvous, with black spots.
