176 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 5 



Size: The largest specimen I have seen Is one from Callao, Peru, 

 secured by Dr. R. E. Coker in 1907 while fisheries advisor to the Peru- 

 vian government. This specimen, a male, measures, median length exclu- 

 sive of rostral plate, approximately 125 mm.; carapace 28; rostral plate 

 6.5. The largest of which I have seen mention is the one in the British 

 Museum, which Miers^^ said was "nearly 5^ inches" long (close to 140 

 mm.). It is probably one of the several specimens from Chile. The largest 

 Hancock specimen is a male from Independencia Bay, Peru, which meas- 

 ures, median length exclusive of rostral plate, 104 mm., carapace 20, 

 rostral plate 5. 



Color: Notes taken on a male from Charles Island, in life: burnt 

 sienna X tawny, with naples to buff yellow flecks ; appendages a golden 

 brown, nearly orange in effect ; fringing hairs of tail-fan aster purple, of 

 antennal scale and pleopods rose purple (colors from Ridgway, Nomen- 

 clature of Colors . . . , 1886). 



Pseudosquilla veleronis, new species 



Distribution: Known only from material dredged by the Hancock 

 Expeditions: Angeles Bay, Gulf of California; Chacahua Bay, Oaxaca, 

 Mexico; and off Petatlan Bay, south and west of the White Friars 

 Islands, Oaxaca, Mexico, the type locality (Hancock Exped. Sta. 264-34, 

 25 fathoms, March 2, 1934). 



Type: A female of perhaps maximum size for the species has been 

 selected as the type (U.S.N.M. No. 76398). In median length exclusive 

 of the rostrum, it measures about 40 mm., carapace 7, rostrum not quite 

 2. A large male, of which the anterior portion of the body and the rap- 

 torial claw is figured, measures about 35 mm., carapace 6.5, rostrum 1.5. 



This species has been named for Captain Hancock's personally de- 

 signed motor cruiser, the Velero III, the excellence of which has con- 

 tributed so much to the success of the expeditions undertaken by Captain 

 Hancock since the year of her launching, 1932. 



Description: Of the Pseudosquillas perhaps an extreme form in 

 the direction of flattened body, trianguliform rostral plate, transversely 

 wide telson, and number of teeth on the raptorial dactylus. 



Body depressed, flattened, with no suggestion of the subcylindrical 

 form characterizing most of the Pseudosquillas. Greatest width of cara- 

 pace little more than median length, exclusive of rostral plate, anterior
