Distribution Previously recorded (see Kott 2002 ): Western Australia ( Barrow I. , Rowley Shoals , Dampier Archipelago , Cape Preston , Montebello Is , North West Cape , Learmouth , Shark Bay , Cervantes ). New records: Queensland (18.845 ° S, 146.795 ° E, 26 m ; 17.655 ° S, 146.225 ° E, 26 m ; 17.145 ° S, 146.205 ° E, 36 m ) . Remarks Although only one to three small specimens were taken at the newly recorded locations, these do establish that the species known formerly only from the northwestern coast of the continent also occurs on the northeastern continental shelf. The species is readily distinguished by its short muscles that do not extend over the lower half of the body, the simple bilabiate anal border with each lip subdivided, the plain-edged oviducal membrane, and projecting distal end of the vas deferens.
