short, strongly deflexed, ending in a rounded knob, deeply 

 channelled above — the channel interrupted just in front of the 

 eyes by three small rounded tubercles on either side. Antero- 

 lateral margins with a rounded eminence crowned by a tubercle, 

 on the hepatic region, followed by a sharp projecting rim formed 

 by nine closely approximated compresssed lobes granulated on 

 their outer borders, the ninth longer than the rest, and with an 

 accessory tooth on its posterior border ; postero-lateral angle 

 armed with a prominent blunt spine with three or four short, 

 blunt branches ; posterior border with two compressed triangular 

 teeth, of which the outer is much the larger, near the postero- 

 lateral angle, and two tubercles on either side above the insertion 

 of the abdomen. Arm with seven or eight irregular compressed 

 triangular teeth on its posterior, and three on its anterior border, 

 four prominent tubercles situated in a longitudinal row on its 

 upper surface ; wrist with a few depressed tubercles ; hand with 

 numerous, mostly granulated tubercles, irregularly scattered on 

 the upper surface, forming several irregular rows on the posterior 

 (external) surface, a row of seven or eight on the anterior 

 (internal) border and another of about half a-dozen on the lower 

 border ; fingers stout, minutely granulated, movable finger with 

 a crest of laciniated teeth above. Ambulatory limbs compressed, 

 carinated, an irregular number of teeth on the carinae ; terminal 

 joint very long and slender. 



Hah. Port Denison, Queensland (3 or 4 fathoms). 



This well-marked species is in many respects intermediate 

 between Parthenope tarpeius of Adams and White, and Parthenope 

 calappoides of the same authors ; it differs, however, from the 

 former in the less flattened tubercles, the presence of the postero- 

 external spine, and the acute lateral margins, the form of the 

 front and other minor points ; and from the latter in the more 

 even surface of the carapace, the absence of the deep pit on the 

 front and the shape of the anterior limbs. Named after Mr. Gr. F. 

 Sandrock, Collector of Customs at Bowen, Queensland, through 

 whose assistance I obtained my first specimen of the species,
