PART 1 GARTH : PACIFIC OXYRHYNCHA 35 



Fab. Entom. p. 402 n. 13" of which the front half of the carapace is 

 missing, as are all of the legs except the chela. This has been stuck onto 

 the fragmentary specimen in such a way as almost completely to hide the 

 abdomen; Dr. Gordon believes, however, that the specimen is a male. 

 It is not labeled "Banks collection", nor is it indicated as type in any way. 

 Since the species ranges from Taltal, Chile, through the Strait of 

 Magellan to the Falkland Islands, thence eastward via the Antarctic 

 islands of South Orkney, Prince Edward, Kerguelen, Macquarie, Camp- 

 bell, and Auckland to New Zealand, the writer sought comparative 

 material from Professor L. R. Richardson of Victoria College, Welling- 

 ton, and obtained a specimen from Macquarie Island, in the latitude of 

 Cape Horn. According to Dr. Richardson, Halicarcinus planatus is a 

 rarity in New Zealand, where it has been confused until recently with a 

 more common species characterized as H. innominata Richardson ( 1949) .

 Inachidae Rathbun, 1905, p. 11. 



Chelipeds specially mobile, rarely much greater than the other legs, 

 or with fingers bent at an angle on the hand. Second article of antenna 

 well developed, generally fused with epistome and often with front. 

 Orbits generally more or less incomplete. Hooked hairs almost always 

 present. Male openings coxal. (Borradaile)

 at the anterointernal angle of the merus. (Alcock)

Key to the Subfamilies of the Family Majidae 



la. Eyes either without orbits, or with incomplete or commencing 



orbits 



2a. Male abdomen terminally broadened, seventh segment sub- 

 quadrate and inserted deeply into sixth segment. Male first 

 pleopod longitudinally grooved, with rows of filamentous 

 setae on either side of groove . . . Oregoniinae 



'Retention of the family name MAJIDAE is contingent upon exercise by the 

 International Commission on Zoological Nomenclature of its plenary powers in 

 validating the name Maja Lamarck, 1801, and in designating as its type species 

 Cancer squinado Herbst, 1788, as requested by Dr. L. B. Holthuis (Bull. Zool. 

 Noraencl., vol. 12, pp. 123-128, 1956).
