A SECOND COLLECTION OF OPISTHOBRANCH MOLLUSCS FROM QUEENSLAND

Introduction

As in the previous paper (Kenny, 1960), complete synonymy has not been listed for the recorded in this Lst. 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 l6lf 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 colJection have been housed at the Queensland Museum, Brisbane.

Records of species

Class OPISTHOBRANCHIA Order CEPHALASPIDEA Suborder PHILINACEA Family PHILINIDAE

One, dredged off Tweed Heads in 25 fm (12/iv/6l); one, dredged near Tangalooma, Moreton Bay on sandy mud (lO/xi/61); one, Shelly Beach near Townsville (19/vi/66) in sandy pool near low water spring. Previously South Australia, New South Wales (Allan, 1950); Victoria (Burn, 1966/); southern Australia (Burn, \ 9(>6d).

Family AGLAIIDAE

Aglaia cyanea (Martens), 1880, as DorUSium, p. 738; Allan, 1950. p. 217, Figs. 3-5. One, Low Is. (15/viiiy63); two. Green 1. (,5/v/(53). in coral reef flat lagoons. Previously E. Africa (Iredale and McMichael, 1962); New South Wales, Victoria, Queensland (Burn, I96bf) 3,s Dorkiiuin.

Order ANASPIDEA Family APLYSIIDAE

Syphonoia geographica (Adams and Reeve), 1850, as Siphonotus, Pt. it, p."44; Baba, 195S, as Pataplysia, p. 39, PI. J, Fig. 2, Text-fig. 3. One, Cairns Harbour (4/ix/6I) dredged; one, Sarina (6/xi/63) sandy beach; one Townsviile Harbour {27lixl66} under rocks on breakwater near low water springs. Previously Japan and Indonesia (Baba, 1955); circumtropical (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 (1950) for P. piperata Smith suggest that this is another synonym.

Aplysia dactylomela Rang, IS28, p. 56, Pi. 12; Baba, 1949, p. 124, FI. 2, Fig. 6, Texc fig. 2; Eales, 1960, p. 307, Figs. 1-8. Numerous specimens, various dates 1961-66, from Magnetic I., Townsville Harbour, Cairns Harbour, Port Douglas, various beaches Cairns south to Mackay. Previously worldwide in warm seas (Eales, i960), Queensland (Burn, 1966b). Complete synonymy is listed by Eales (I960) and discussed by Kay (1965). One of the TownsviJle 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.

(Marcus, 1965); New South Wales (Ailan, 1950). 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 Mart>;n’s publication has been rejected by the International Commission on Nomenclature, Kay (1965) has reviewed the synonymy of the species. -

Alton (19326) discussed the similarities and differences between P. scabra, P. coriacm, Abraham 1877, and P. iredalei and Marcus and Marcus (1960) have listed the synonymy. As the present collection includes material ranging through almost all the colour and superficial variations noted for the three species, the Cuvier name has been used here. Kenny (1960) used the Allan name. Family HEXABRANCfflDAE

Family GLAUCIDAE

Four, Mission Beach, near Tully (l/iv/6 6 ). Previously widespread warm water pelagic; Australian records from New South Wales (Iredale and McMichael, 1962; Bennett, 1966). Bennett (1966) has commented on synonymy and pointed out that many past records of G. lineatus, from Australian waters, should be referred to this species. Spawning The 4 species for which egg masses were observed (Pleurobranchus hilli, Pleuro- branchus mamittatus, lineolata, Asteronotus cespitosus) were all collected in the Townsville, Magnetic Island area and all spawned in the July, August period. This period of the year is the time of lowest inshore temperatures in this area. The sea surface temperatures outside the Townsville harbour breakwater recorded during July and August range from 20.4°C to 22.5‘^C (27 readings at various dates). ZoofBography Of the 49 species listed in this paper, 23 have not previously been reported from Queensland and 9 of these are new records for Australia. This collection plus the recorded geographic distribution of these species from the literature suggests that the opisthobranch fauna of the Indo-West Pacific region is relatively uniform (see also Kenny, 1960). Of the species listed, 4 can be described as widespread tropical forms, 22 as having a wide Indo- I^cific range, 14 as occurring throi^hout the western Pacific from eastern Austraha to Japan and 9 noted only in the south-west Pacific area.

AcJcnowiedgments

The author is indebted to the members of staff and students of the Townsville University College who assisted with the collection of much of the material. The Zaoiogy Department, University of Queensland, and Dr. J. Barnes (Cairns) provided several specimens. Special thanks are due to Mr. R. Burn (Honorary Associate in Conchology, National Museum, Melbourne) for his considerable assistance with literature, and for reading and criticizing the manuscript.
