MARINE GAMMARIDEAN AMPHIPODA 227 



gnathopods not eusirid, subchelate, article 5 nearly as long as 6, not 

 lobate; pereopods 3-5 with articles 4-6 each not longer than article 

 2; postantennal cephalic angle presumably rounded {Atyloella); rostrum 

 reaching end of article 1 oj antenna 1 (Paramoera). Species: 1, antarctic, 

 littoral. 



Meteusiroides Pirlot 



Meteusiroides Pirlot, 1934. 



Type-species: M. keyensis Pirlot, 1934 (original designation). 



Accessory flagellum absent; lower lip with large inner lobes, outer 

 lobes very widely spread (Pontogeneia)*; inner plate of maxilla 1 with 

 four or fewer terminal setae; gnathopods not eusirid, subchelate, 

 article 5 lobate, shorter than article 6; pereopods 3-5 with articles 

 4-6 each not longer than article 2. Species: 2, Indonesia, N. Atlantic, 

 bathyal to abyssal. 



* Apparently inner lobes shown by Pirlot (1934), are horizontal basal processes 

 unnaturally flattened and outer lobes therefore excessively spread; small inner 

 lobes present as in Pontogeneia; information from antarctic individual of Mete- 

 usiroides (possible new species in colls, of El Tanin expeds.). Meteusiroides has 

 telson extending 3/4 along rami of uropod 3, whereas telson of Pontogeneia extends 

 only 1/3 along rami of uropod 3. Also Meteusiriodes has small adze-shaped process 

 on epistome and might be confused with Atyloella.

Accessory flagellum articulate, of medium length; lower lip with 

 inner lobes indistinct or absent; inner plate of maxilla 1 densely 

 setose along medial edge; gnathopods not eusirid, subchelate, article 5 

 not lobate, shorter than article 6; pereopods 3-5 with articles 4-6 each 

 not longer than article 2; rostrum inconspicuous (Liouvillea) . Species: 

 28, bipolar, coldwater, littoral.
