Boone, Crustacea, Cruises of "Ara" and "Alva" 255 



Discussion : This unusually beautiful, edible prawn is again 

 reported in the Vanderbilt Collection, this time from the Philip- 

 pines, apparently establishing the second Philippine record for 

 it, the first having been reported by Mr. Bate from the "Chal- 

 lenger" collections (1886). The present specimens, an adult 

 male, measuring 8.75 inches from apex of rostrum to apex of 

 telson, and a female, measuring 7.13 inches, in the same line, 

 were secured by the "Ara" World Cruise and contribute the first 

 record of the colour of the living prawn, which Mr. Vanderbilt 

 described in his field notes as follows : "Colour of body brownish- 

 pink along the segments, legs coral-red, eyes blue-green." It was 

 captured by the "Alva" World Cruise at Noumea, New Cale- 

 donia, and is fully described and figured in Volume VI, Bulletin 

 of the Vanderbilt Marine Museum, 1935, p. 96, pi. 24, text ngure 7.

Name : caementarius : a mason. 



Type : This species, first published anonymously in 1776, by 

 the Abbe Don Juan Ignacio Molina, and republished under his 

 own name in 1782, was based upon his natural history collec- 

 tions made in Chile, while resident there, and left in Chile when 

 he, like others of the Jesuit order, was expelled. His manuscripts 

 relating to this collection were recovered and sent to him in Italy ; 

 they are deposited in Bologna, Italy. 



Herr Poeppig (1836) redescribed the species in greater de- 

 tail, from specimens obtained from the freshwater streams of 

 Aconcagua, Chile, in the "Mus. Zool. Lips, ac Soc. Nat. Curios, 

 etc." 



Dr. Henri Milne Edwards (1837) described the same species 

 as Palaemon gaudichaudi, from material collected in Chile by M. 

 Gaudichaud and deposited in the Paris Museum. In 1843 Dr. 

 Milne Edwards and M. Lucas published an excellent colour figure 

 of this species, made by M. Valliant, showing the shrimp to be
