dolioform; the 2nd segment is larger, stronger, and broadened distally; the 

 3rd segment is narrow, conical. Maxillae I have a broad, single-segmented 

 palp, bear one seta in the distal part, and have a slightly denticulate inner 

 margin; the outer lobes are pubescent in the distal part and bear a few 

 (five) short stout spines; the inner lobes are broad with a smoothly curved 

 distal margin. The lobes of maxillae II are nearly equal in length and width 

 and have an incised distal margin provided with long, stout spines. The 

 maxillipeds have elongated-oval outer lobes armed with stout setae and 

 relatively short, weakly pubescent inner lobes. 



The relative length of the pereopods is variable. In sexually mature 

 individuals, pereopods I are short, stout, with a broad 2nd segment, their 

 3rd and 4th segments short; the 5th segment is highly broadened dis- 

 tally so that its maximum width equals its length and the anterior and 

 posterior distal corners form round lobes; the 6th segment is conical 

 with a straight posterior and slightly protruding (sometimes straight or 

 even concave) anterior margin forming a small denticle over the claw; 

 the 6th segment is slightly longer than its maximum width; the claw is 

 straight. Pereopods II are much longer than pereopods I; their 2nd seg- 

 ment is equal in width to pereopods I but almost 1.5 times longer; the 

 5th segment is slightly broadened distally so that its maximum width is 

 almost 2/5 its length; the 6th segment is narrow, conical, slightly shorter 

 than the 5th and its posterior margin concave. Pereopods III and IV are 

 nearly equal in length; their 2nd segment is broadened, shorter than the 

 4th and 5th together; the 6th segment is thin, longer than the 5th but 

 shorter than the 4th; the claw is almost straight. Pereopods V are longer 

 than pereopods IV; their linear or broadened 2nd segment is longer than 

 the 4th, the latter 1.5 times longer than the 5th; the 6th segment is longer 

 than or equal to the 5th. Pereopods VI are longer and stronger than pere- 

 opods V, in typical forms slightly longer than the pereon; the width of 

 the 2nd segment is the same as in pereopods I and II (fairly often, par- 

 ticularly in young individuals, it is appreciably shorter); the 4th segment 

 is strong, only slightly shorter than the 2nd; the 5th segment is slightly 

 arcuate, equal to or slightly longer and appreciably thinner than the 4th 

 segment; the rod-shaped 6th segment is much longer than the 4th. Pere- 

 opods VII are half the length of pereopods VI and weak. The claws of 

 pereopods V-VII are retractile, stout, and curved. 



The uropods are short and broad; their rami are narrowly lanceolate 

 in uropods I, broader in uropods II, and broadly lanceolate in uropods III. 

 The telson is equal to or longer than the basipodite of uropods III, nar- 

 rows distally, and is apically rounded. 



Notes: Lanceola sayana is possibly identical to L. pelagica, described 

 by Say (1818). This fact has been reported by many authors, including 

 Stebbing (1888) and Bovallius (1885b), who described L. sayana.
