Plate 8. 



Type: Described without specific locality cited, in Risso's "Histoire 

 Naturelle des Crustaces des Alpes Maritimes. ' ' 



Distribution: Mediterranean Sea and the adjacent shores of the 

 Atlantic Ocean, the coasts of Spain and Portugal, also the Canaries, 

 Madeira and the Cape Verde Islands. 



Material examined : Ten specimens dredged in 65 fathoms, eleven 

 miles N. W. of Lissa Island, Dalmatia, Adriatic Sea, September 13, 

 1924, by the ''Ara," William K. Vanderbilt, commanding. 



Technical description : Precervical region of the carapace widest 

 anteriorly, with the frontal margin rounded in the median region, lat- 

 eral points shallow, acute, another minute tooth at the anterolateral 

 angle; postlateral margin convex; posteervical region soft, tumid; 

 abdomen asymmetrical, coiled, the pretelsonic segment with a broad, 

 rectangular, calcareous plate; proximal part of the telson unequal- 

 sided, smaller than the plate on the preceding segment, distal part 

 of the telson flexed under, one and one-half times as long as the proxi- 

 mal section, with the lateral margins convex, each with a short in- 

 cision, and are a little convergent distally ; the distal margin is a little 

 incised by a V-shaped sinus and bears a few spinules. There are three 

 abdominal appendages on the left side ; each appendage has the pedun- 

 cle approximately as long and wide as the subequal blades. 



The ocular scale is lobate, with the apex acuminate. The eyestalks 

 are short, thick, wider distally, the cornea terminal, spherical, of 

 greater diameter than the stalk, shining black. 



The antennulae are slender, about two and one-half times the length 

 of the eyestalk, the first and second joints combined reaching as far 

 forward as the eye, the third joint about equal to the two preceding ; 

 the flagellum very short, the upper branch with a brush of cilia. 



The antennae are small, the first article wide and short, an acute 

 point at the inner distal angle ; the acicule is slender, sickle-shape, the 

 tip directed outward and reaching quite as far forward as three-fifths 

 of the length of the third article ; the second article is very short ; the 

 third article is quite slender, cylindrical, about as long as the first and 

 second taken together; the flagellum is multiarticulate, very slender, 

 extending as far forward as the tip of the great cheliped. 



The chelipeds are decidedly unequal, the right being much the 

 larger. The merus reaches as far forward as the tip of the eyestalk ;
