NO. 3570 PANDARIDAE — CRESSET 29 



spicuous. Cephalic appendages like those of female except for 

 maxilliped (fig. 144) . 



Legs 1-4 biramose and with spine and setal formula as follows: 



Leg 5 (fig. 145) located on midlateral edges of genital segment and 

 consisting of 3 plumose setae and 1 short stout spine. Leg 6 (fig. 

 146) located near junction of abdomen and genital segment and 

 composed of a single plumose seta and a short spine. 



Yy.'E.uh.uK^.—Gangliopus pyriformis is apparently cosmopolitan in 

 distribution and occurs commonly on the gills of the blue shark, 

 Prionace glauca. In 1960 Yamaguti and Yamasu described a new 

 species Gangliopus tetrapteri. Since they do not refer to the work of 

 Monod and Dollfus (1938), it is assumed that they were not aware 

 of it. They based their new species on morphological differences 

 which do not exist. Gerstaecker originally described the female 

 as having a 2-segmented abdomen. His original description was very 

 superficial. Monod and Dollfus (1938) updated the work and 

 provided a working description. Gangliopus tetrapteri does not differ 

 from this later description nor from my own collections in the Indian 

 Ocean. The male was described under the name Nogagus angustulus 

 by Gerstaecker at the same time as the female. No description of 

 the male has appeared since then. I have added salient features 

 to this original description.
