FISHERY BULLETIN: VOL. 85, NO. 2 



Only a few of the available specimens of this 

 species still have entire pereopods, and even fewer 

 have retained all 5 pereopods; in almost all, the 

 fourth and fifth are missing, or only two or three 

 podomeres are represented. The data obtained by 

 me, however, seem to confirm those presented by 

 De Man (1911) and Crosnier (1978), which indicate 

 that the pereopods of P. kathleenae are more slender 

 than those of P. sibogae. Their data were based on 

 a female 31 mm CL collected by the Siboga Expedi- 

 tion and identified by them as "crassipes". This 

 specimen was examined during the present study 

 and is assigned herein to P. kathleenae. 



Etymology.— I take pleasure in naming this shrimp 

 for my daughter Kathleen P. Canet.

Diagnosis.— Optic calathus relatively short, mesial 

 margin 0.9-1.1 times distal width. Anterolateral 

 carina lacking. Ventral extremity of cervical carina 

 forming sharp-edged arc. Posterior extremity of 

 hepatic sulcus turned ventrally. Third article of 

 antennular peduncle not expanded laterally; males 

 with ventral antennular flagellum not sinuous and 

 ultimate article of third maxilliped twisted, marked- 

 ly dilated proximally, less so distally, and bearing 

 ventrolateral rows of minute spines. Pereopods not 

 covered with minute setae. Petasma with distal two- 

 thirds of ventral costa turned rather abruptly disto- 

 mesially and ventral surface of dorsolateral lobule 

 lacking setae. Thelycum with plate of sternite XIV 

 long and produced in short anterolateral hoods; me- 

 dian plate of sternite XIII moderately long (not near- 

 ly reaching spine on sternite XII), rather narrow 

 (maximum width 0.45-0.55 length), and not ex- 

 panded posterolaterally in conspicuous prominences. 



Description.— Body slender, densely studded with 

 minute setae. Rostrum in males (complete only in 

 two) relatively short, its length 0.2 and 0.7 CL, and 

 tapering gradually to sharp apex; in females longer.
