The basipodite of uropods I sometimes has a finely denticulate distal 

 part in the anterior margin; the rami are lanceolate and equal in length to 

 the basipodite. The rami of uropods II are lanceolate; both margins of the 

 endopodite are denticulate, in the exopodite only the posterior margin. 

 The basipodite of uropods III is half as long as wide; the endopodite 

 is oval and has smooth margins; the exopodite is narrower and has a 

 smooth anterior and denticulate posterior margin. The telson is short, 

 has a rounded tip, is approximately equal in length and width, its length 

 1/4 that of the last urosomite. 



Distribution: A circumtropical species. It is found in the Adantic 

 (south of 34° N), Indian (Zanzibar), and Pacific (Gulf of California, Peru- 

 vian region, northeastern Australia, New Zealand, Hawaiian Islands, Sulu 

 Sea, Kuroshio, South China Sea) oceans, and in the Mediterranean Sea. 



3. Parapronoe campbelli Stebbing, 1888 (Fig. 201) 



Stebbing, 1888: 1522. 



Length of adult females up to 15 mm, of males 10 mm. 



The body is less massive than in P. crustulum and better propor- 

 tioned; in females the head is slightly narrowed anteriorly. 



The distal process of the 5th segment of pereopods II has straight den- 

 ticulate margins, and its tip reaches the base of the claw. The 2nd segment 

 of pereopods V is highly bulged, oval, and more than 2.2 to 2.5 times 



374 longer than wide. The 2nd segment of pereopods VI is more elongated 

 than in pereopods V and its length almost twice its maximum width. 



The basipodite of uropods I is shorter than the rami; the rami are 

 thin and long; the exopodite has a smooth anterior margin. The exopodite 

 of uropods III has a smooth anterior margin and a denticulate posterior 

 margin; both margins of the endopodite are smooth. The telson is broadly 

 lanceolate, its length twice its width and about 2/3 the length of the last 

 urosomite. 



Notes: Shoemaker (1945a) suggested that Stebbing had described 

 some sexually immature specimens of P. crustulum as a new species, 



375 P. campbelli. However, we found a male 10 mm in length and a gravid 

 female 15 mm in length in the collections from the environs of New 

 Zealand. These specimens completely accord with the description and 

 drawing given by Stebbing and differ sharply from P. crustulum in struc- 

 ture of pereopods II and proportions of pereopods V and VI, the uropods, 

 and the telson. 



Distribution: Known from the Indian (eastern part) and Pacific (south 

 of 35° N in the zone of Kuroshio, environs of New Zealand) oceans.
