Chap, xvi.] LINGULA AND LBIULUS. 347 



of a single splinter of bamboo, the vibrating tongue being 

 extremely delicately shaped ; the tongue is cleverly weighted 

 by means of a knob of the wood left projecting on its back. 

 The instrument produces a tone indistinguishable from that 

 of a metal Jew's-harp ; it is quite unlike Melanesian bamboo 

 Jew's-harps in its form. 



A sharp tide runs in the channel between Zamboanga and the 

 Island of Santa Cruz Major, which lies just opposite the town. 

 In the tide-way, whether the water was running up or down, a 

 most unusual abundance and variety of surface-living oceanic 

 animals and larvas of shore forms, was obtained with the 

 towing net ; amongst these were Tornaria, and larvae of Sipun- 

 ciilids and Chirodota. The place would be a most convenient 

 and productive one to a working zoologist. 



The Brachiopod Lingula is so abundant in shallow water 

 close to the town, that two boys gathered more than a hundred 

 specimens at a single low tide at the request of Von Willemoes 

 Suhm. Unfortunately the much prized " mariske " did not 

 reach the " Challenger." The boy with his bottle full was met 

 by a rival collector, who completed a bargain forthwith. There 

 are rival collectors even at Zamboanga, and we suspected, I do 

 not know whether righdy or not, that it was a natural-history 

 collector from the United States who was in the neighbour- 

 hood at the time, who had thus been lucky enough to liecome 

 possessed of our expected treasure. 



A King Cral) {Limiiliis I'otundicaiidatus), is not uncommon 

 near Zamboanga; it is called " cancreio." Von Suhm thought 

 that he had obtained a series of young larvae of Limulus 

 amongst the surface animals collected by the net, but he 

 subsequently came to the conclusion that he had been mis- 

 taken. At low tide, by wading and turning over stones, 

 enormous Planarians of the genus Thysanozoon are to be 

 found in plenty ; they are of a dark purple colour, and measure, 

 some of them, as much as five inches in length, and two inches 

 in breadth. 



I accompanied Von Willemoes Suhm on a visit to the 

 Island of Santa Cruz Major. We sailed over in a Moro canoe 

 managed by two of these natives ; the boat was armed with a 

 large number of bamboo spears, simple light bamboos cut off 

 slanting at one end so as to form a sharp cutting point like 

 that of a quill tooth-pick in shape. A bamboo so cut is 

 extremely sharp, and the spears must be formidable weapons, 

 especially against a thinly clad adversary. Two or three dozens 

 of these spears were placed on rests on either gunwale, and 

 there were besides two round shields of a kind of basket-work 

 in the boat.
