QUEENSLAND FAUNISTIC RECORDS PART IX A SECOND COLLECTION OF OPISTHOBRANCH MOLLUSCS FROM QUEENSLAND Introduction As in the previous paper (Kenny, 1960), complete synonymy has not been listed for the species recorded in this list. Instead, recent and readily available references have been given. The classification used is basically that of Odhner (1936). Most specimens listed in the 1960 report had been collected in southern Queensland, but the present collection is predominantly from tropical Queensland. The two collections add up to more than 440 specimens including 58 species. Many species, previously recorded from Queensland, have not been noted from these collections and almost lfcllf the species listed here were not recorded from the 1960 collection. From this collection, one specimen of each species listed has been retained at the University College of Townsville. The remaining material and the specimens from the 1960 collection have been housed at the Queensland Museum, Brisbane. Records of species Class OPISTHOBRANCHIA Order CEPHALASPIDEA Suborder PHILINACEA Family PHILINIDAE Philine angasi (Crosse and Fischer), 1865, as Bullaea. p. 38, Pl. 2, Fig. 8; Allan, 1950, p. 203, Text-fig. 46. One, dredged off Tweed Heads in 25 fm (12/iv/6 1 ); one, dredged near Tangalooma, Moreton Bay on sandy mud (10/xi/6 1); one, Shelly Beach near Townsville (19/vi/66) in sandy pool near low water spring. Previously South Australia, New South Wales (Allan, 195 0); Victoria (Burn, 19661); southern Australia (Burn, 1966d). Family AGLAIIDAE Aglaia cyanea (Martens), 1880, as Doridium, p. 738; Allan, 1950, p. 217, Figs. 3-5. 83 84 RUN kFNNY One, Low Is. (15 /viii/63): two. Green l. (5/v/b3). in coral reef tlat lagoons. Previously E. Africa (Iredale and tlktllichael, 1962): New South Wales, Victoria, Queensland (Burn, 1966/) as Doridiunz. Order ANASPIDEA Family APLYSIIDAE Syphonota geographica (Adams and Reeve), 1850, as Siphonotus, Pt. 3, p. 44; Baba, 1955, as Paraplysia, p. 39, Pl. 1, Fig. 2, Text-fig. 3. One, Cairns Harbour (4/ix/6 1) dredged; one, Sarina (6/xi/63) sandy beach; one Townsville Harbour (27/ix/66) under rocks on breakwater near low water springs. Previously Japan and Indonesia (Baba, 195 5); circumtropica1 (Eales, 1960). Eales (1960) clearly states the synonymy of Paraplysia geographica with this species by listing Baba's (1955) illustration. Baba, however, designates the illustration as P. geographica scripta Bergh 1905 . The description and text-figure given by Allan (195 0) for P. piperata Smith suggest that this is another synonym. Aplysia dactylomela Rang, 1828, p. 56, Pl. 12; Baba, 1949, p. 124, Pl. 2, Fig. 6, Text-fig. 2; Eales, 1960, p. 307, Figs. 1-8. Numerous specimens, various dates 1961-66, from Magnetic 1., Townsville Harbour, Cairns Harbour, Port Douglas, various beaches Cairns south to Mackay. Previously worldwide in warm seas (Eales, 1960), Queensland (Burn, 1966b) . Complete synonymy is listed by Eales (1960) and discussed by Kay (1965). One of the Townsville Harbour specimens conformed to the colour pattern shown by Baba (1949), being a bright pink with purple markings, but all other specimens tended to be brown or olive green. Aplysia extraordinaris Allan, 1932a, as Tethys, p. 319, Pl. 35, Figs . 7-8; Eales, 1960, p. 312, Fig. 22.

Previously Japan (Baba, 1949); circumtropical (Kay, 1965 ) as D. scapula; Caroline Is. , Guam and Palau I. (Marcus, 1965 ); New South Wales (Allan, 195 0). Although this species is frequently listed as D. scapula (Martyn, 1784), it has been pointed out by Marcus (1965 ) that this name is invalid as Martyn's publication has been rejected by the International Commission on Nomenclature. Kay (196S) has reviewed the synonymy of the species. Bursa tel/a /eachii Blain ville, 18 17, p. 138; Baba, 1949, as Notarchus, p. 128, Pl. 5, Fig. 19, Text-figs. 12, 14; Allan, 1950, p. 215.
