280 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 5 [ 



Ovigera: Ten-jointed, the 1st short, 2nd and 3rd about equal and a 

 little longer than the 1st. The 4th is about twice as long as the first 3. The I 

 5th is more slender and longer than the 4th and is swollen at the distal , 

 end. The 6th is shorter, with many small hairs on its ventral side. The i 

 7th is shorter than the 6th, with an even row of about 13 elongate spines j 

 on its ventral side. Each spine has lateral extensions. The 8th joint is i 

 shorter than the 7th. The 9th and 10th are about equal to the 7th in j 

 length and are similarly armed with spines. The 10th segment bears a i 

 long terminal claw with teeth on its lower margin. j 



Ambulatory legs: Not veiy hairy, about 37 mm. long; the 1st coxa 1 

 is the shortest of the three, and the 2nd is the longest. The femur is quite i 

 long and is curved ventrally. The 1st tibia is a little longer and the | 

 2nd tibia is the longest leg joint. The 1st tarsus is longer than the 2nd. I 

 The terminal leg claw is well developed, and the paired claws are about 

 % as long. i 



Measurements: The proboscis is about 2 mm., with the neck region 

 about 1.7 mm. The 1st body segment is slightly longer than the 2nd. The ij 

 lateral processes are a little longer than the abdominal appendage. [ 



Comparisons : This species resembles A^. rneridionale and N. hie- 

 male, but the 1st segment of the cheliforus is shorter than the proboscis. 



Material studied 



One specimen, Station 575-36, north of San Pedro Nolasco Island, 

 Gulf of California, March 12, 1936, 100 fms. 



One young specimen. Station 719-37, Lower California, Consag , 

 Rock, March 24, 1937, 10-25 fms. 



One male. No. 3856, Redondo Beach, California. Collected by Burch. 



One female. Station 1185-40, southern California coast, Septem- 

 ber 28, 1940, 50 fms. 



Two females, 1 male with eggs. Station 909-39, Catalina Island, 

 Emerald Bay, 2 miles off shore, Jan. 28, 1939, 65-90 fms. 



One female and 1 young. Station 1181-40, southern California coast, 

 Sept. 10, 1940, 47 fms. 



One female. Station 978-39, Santa Barbara Island, east of Gull r 

 Island, May 28, 1939, 21-28 fms. 



In addition, I have abundant material from about 2 dozen localities 

 off the west coast of North America. These and other records at my dis- 

 posal give this range from the Canadian border down to Lower Cali- 

 fornia. This species is a very common one in waters of moderate depth. 

 Most of the records are of specimens not many miles off shore.
