Penaeopsis macleayi (Haswell) 



Plate 19 



Type: The type was collected at Port Jackson, New South 

 Wales, and is a specimen about five inches long ; it is deposited in 

 the MacLeay Museum at Sydney. 



Distribution : The "Alva" specimens, twelve in number, from 

 New Caledonia, represent the first record of this species taken 

 outside of the coast of New South Wales, where it was originally 

 found at Port Jackson (Haswell, Schmitt) ; de Man recorded two 

 specimens from Sydney ; Ogilby recorded it from the Sydney mar- 

 ket; Miers reported from Richmond River, New South Wales; 

 Whitelegge had two specimens from off Schoalhaven Bight, 

 "Thetis" Station 50, depth 15-18 fathoms ; A. R. McCulloch col- 

 lected it at Fullerton Cove Bay and at Hawkesbury River, accord- 

 ing to Schmitt. Phillipps reported it as the less important of the 

 two species of edible shrimp, "abundant in the waters of New 

 South Wales; imported in April from the Sydney market into 

 New Zealand." 



Material examined : Ten males and two females collected in 

 Noumea, New Caledonia, September 19, 1931, by the "Alva." 



Technical description : Rostrum nearly straight, with slight 

 upward curvature towards the tip, extending to about midway 

 the third peduncular article of the antennulae and armed with 

 one epigastric and eight rostral spines on the upper margin, these 

 set in subequal sequence from above the orbital angle to about 

 opposite the base of the second peduncular article of the anten- 

 nulae. The postrostral carina is continuous backward for about 

 three-fifths of the length of the carapace and is accompanied on 

 either side basally by a lateral ridge, which accentuates the thick-
