288 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 5 



Several specimens from Laguna Beach agree in most respects with 

 Hall's descriptions. However, I am inclined to the opinion that this and 

 the next described species may be the same. The chief difference between 

 them seems to be the position of the lateral processes, which are closer 

 together in this species. 



One specimen, Station 1184-40, Indian Rock off Catalina Island, 

 Sept. 11, 1940, 46 fms.

Anoplodactylus robustus Hilton, Jour. Ent. and Zool., vol. 21, 1939, 

 p. 28. 



Characteristics: Body heavy. Legs rather long, heavy. Second tarsus 

 with 3 long spines in its basal region and many smaller ones farther along. 

 Median tarsal claw long, moderately slender, with a narrow free edge 

 below. Paired tarsal claws slender, small. Body heavily chitinized, mod- 

 erately pitted. Attachment discs on the under sides of the base of the 

 proboscis. 



Description 



Color: Dark brown, red brown, or often greenish; after preserva- 

 tion the color may be pink or red. 



Body: Rather robust, elongate. Segments marked by prominent su- 

 ture lines. Lateral processes about as broad as the ventral part of the body, 

 each with a slight knob on its distal dorsal border. The 1st process is di- 

 rected forward; the 2nd, straight out; the 3rd and 4th directed back- 

 ward. The last 2 are contiguous at their base. The 1st or ocular segment 

 roughly pointed in front, with the neck bearing the eye tubercle continued 

 forward over the base of the proboscis. Just above, where the ovigers come 

 off, are 2 little processes slightly in front of the 1st lateral process. There 

 are 3 suture lines across the body: the 1st just back of the 1st pair of 

 lateral processes, the 2nd just back of the 2nd pair of lateral processes, 

 and the 3rd back of the 3rd pair of legs. 



Ocular elevation: Quite high and situated on the short neck, from 

 which the chelifori take origin. It is pointed straight up and runs to a 

 sharp tip. At its base are 4 well-developed eyes, quite deeply pigmented. 



Proboscis: Irregularly cylindrical, swollen slightly at the center and 

 at the ends. Shorter than the body. 



Abdo7)iinal segment: This is rather slender and quite long. It points 

 straight up and is slightly smaller at its tip.
