Distribution: Known from many places in the Atlantic Ocean, from 

 Greenland (63° 19' N, 26° 50' W) to the Bermuda and Azores islands, and 



118 the Gulf of Guinea. In the Indian Ocean it is found from the Arabian 

 Sea and Malayan Archipelago to 35° S. In the Pacific Ocean it has 

 been reported from the Kuril-Kamchatka region as well as tropical and 

 equatorial regions of the western part of the ocean. Young individuals 

 have been found in catches from depths of 200-1 ,000 m and the casts of 

 spawned females right at the surface. 



3. Mimonectes spandli Stephensen and Pirlot, 1931 (Fig. 49) 



Stephensen and Pirlot, 1931: 532; Shoemaker, 1945a: 244.—steen- 

 strupi (non steenstmpi Bovallius, 1885a); Pirlot, 1929: 46. 



Length of sexually mature specimens 7-15 mm. 



Antennae I have a three-segmented peduncle; the proximal segment 

 of the flagellum (in females) is fairly broad and conical, the distal seg- 

 ments large, of which the conical apical segment is narrower but longer 

 than the two preceding segments. 



The mandibles are narrow with a finely denticulate cutting edge and 

 a small accessory plate. The lobes of maxillae I are highly pubescent, the 

 inner lobe small and oval. The lobes of maxillae II are narrow, the outer 



119 lobe slightly shorter but broader than the inner. The outer lobe of the 

 maxillipeds is oval with a rounded distal angle, and armed on the inner 

 margin with sparse setae; the inner lobe is short and not deeply split. 



The pereopods are short and strong with broad segments. In sexually 

 mature females pereopods I-V have a broad 2nd segment. The 2nd seg- 

 ment of pereopods I is longer than the 5th and 6th together; the conical 

 6th segment is slightly longer than the 5th or equal to it; the claw is 

 long, strong, and almost straight. In pereopods II the narrowly conical 

 6th segment is appreciably longer than the 5th and the claw is straight. 

 Pereopods III and IV are the longest of all, the 4th segment unusually 

 short — only slightly longer than the 3rd and less than half the length 

 of the 5th segment; the narrow 6th segment is shorter than the 5th; the 

 claws are strong and almost straight. Pereopods V and VI have identical 

 ratios but pereopods V are slightly longer; the 2nd segment is slightly 

 larger than the 3rd, 4th, and 5th together; the 4th segment is very short, 

 less than half the length of the 3rd; the conical 6th segment is shorter 

 and narrower than the broad 5th segment; the claws are long, strong, 

 and slightly curved. Pereopods VII are shorter and much weaker than 

 pereopods VI though with nearly the same length ratios of the various 

 segments. 



Distribution: Boreal and subtropical regions of the Atlantic Ocean 

 (38°20' N, 9°20' W; 34°41' N, 9°30' W and vicinity of the Bermuda 

 Islands).
