The 5th segment of pereopods I has no distal process, is weakly 

 broadened, and the posterior margin armed with a few submarginal setae; 

 the 6th segment is slightly recurved. The 5th segment of pereopods 11 has 

 a small pointed posterior distal process 1/4 the length of the 6th segment 

 and the posterior margin is also armed with a few submarginal setae; 

 the 6th segment is straight and longer than the 5th. The 2nd segment 

 of pereopods V is oval and has a medially bulged anterior margin, with 

 450 a notch in the distal margin into which the 3rd segment fits. The distal 

 segments of pereopods VI together are shorter than the 2nd segment; the 

 2nd segment has a short semilunar lateral "fissure", its anterior margin is 

 bulged, and the posterior margin bulged in the proximal part but straight 

 in the distal; the 4th segment has a short distal process. Pereopods VII 

 consist only of the 2nd segment, which is strongly tapered distally; apical 

 segments are absent. 



The rami of all the uropods are lanceolate and equal in length 

 in uropods I. The endopodite of uropods II and III is larger than the 

 exopodite and fused in uropods III with the basipodite, twice longer 

 than the exopodite and thrice broader. The telson is approximately 2/3 

 the last urosomite in length. 



Distribution: The species is known from the Mediterranean Sea and 

 the Atlantic (between 7 and 22° N, environs of Cape of Good Hope) 

 and Indian (eastern part) oceans.

2. Paratyphis parvus Claus, 1887 (Fig. 241) 



Claus, 1887 40.— pacificus Stebbing, 1888: 1479. 



Length of adult specimens up to 4 mm. 



The height of the head is approximately twice its length. The 2nd 

 and 3rd segments of antennae II in males are the same length; the 4th 

 segment 2/3 and the 5th segment 1/2 their length. 



The 2nd segments of pereopods I is linear, narrow, and long; the 

 3rd-7th segments together are almost 2/3 the 2nd segment in length; the 

 4th and 5th segments are approximately equal in length; the posterior dis- 

 tal process of the 5th segment of pereopods I is very short and looks like 

 a barely stretched angle with a finely denticulate posterior margin, while 

 in pereopods II this process is narrow, 1/3 the length of the 6th segment, 

 and both its margins are denticulate; the 6th segment of pereopods I and 

 II tapers distally, its margins are almost straight, and the posterior mar- 

 gin very finely denticulate. The 2nd segment of pereopods V is oval, has 

 a notch on the distal margin into which the 3rd segment fits, and the 

 anterior margin is medially undulating; the 3rd-7th segments together 

 are almost equal to the 2nd segment; the 4th and 5th segments have a 

 finely pectinate anterior margin; the 6th segment is armed with very fine 

 marginal and submarginal spinules. The 2nd segment of pereopods VI
