The uropods and telson are as in P. maculatus. 



Distribution: The species is known from the Atlantic (region of 

 Lagos) and Pacific (southern Hawaiian Islands, Kuroshio, Nasca ridge) 

 oceans. 



3. Paratyphis spinosus Spandl, 1924 (Fig. 242) 



Spandl, 1924: 36. — clausi Stephensen, 1925a: 221. 



Length of adult specimens 5-6 mm. 



Antennae I in males are the same as in P. maculatus. The basal 

 segment of antennae II in males is half the 2nd segment in length, the 

 4th less than half the 3rd, and the 5th slightly longer than the 4th. 



The 2nd segment of pereopods I is 1.5 times longer than the rest 

 together; the 4th segment is slightly broadened and bears two long setae 

 along each of its margins; the 5th is longer than the 4th, its margins 

 slightly bulged, the anterior bearing two-three, the posterior five-six 

 setae, and the distal process is absent. The 2nd segment of pereopods II 

 is longer than in pereopods I; the 4th segment bears three setae on its 

 posterior margin; the 5th segment has a rounded distal process 1/4-1/3 



452 the length of the 6th segment, its anterior margin armed with two setae, 

 and the posterior margin together with the distal process has about ten 

 marginal and submarginal setae. The 2nd segment of pereopods V is 

 oval, without a distal notch, with even margins, and 2-2.3 times longer 

 than wide; the 3rd-7th segments together are shorter than the 2nd; the 

 4th-6th segments are armed with two-three setae on the anterior mar- 

 gin; the claw is short and almost straight. The 2nd segment of pere- 

 opods VI has a barely bulged anterior margin, with one shallow notch 

 each in the proximal and distal parts, the posterior margin is strongly 

 bulged in the proximal part and almost straight in the distal, the lateral 

 fissure extended, narrow and not so long, only 2/7-1/4 the segment in 

 length; the 4th segment has a distal process that is narrower than that in 

 either P. parvus or P. maculatus. Pereopods VII consist of a 2nd segment 

 that is broadened and strongly bent forward and one-three rudimentary 

 distal segments; the 2nd segment is more stretched in females than in 

 males. 



In uropods I the anterior margin of the basipodite is denticulate; the 

 rami are lanceolate; the endopodite is equal to the basipodite in length 

 but somewhat longer than the exopodite. The basipodite of uropods II is 

 equal in length and width; the endopodite is distally narrowed and longer 



453 and broader than the exopodite. The endopodite of uropods III is fused 

 with the basipodite and sharply narrowed in the distal part. The telson 

 is smoothly rounded or has a stretched tip. 



Distribution: Known from the Mediterranean and Red seas, eastern 

 region of the Indian Ocean, and Peruvian region of the Pacific Ocean.
