BIOLOGICAL SURVEY OF TRINOoiviALEE HARBOUll. 37 



At this and the next two stations the soft sand made dredging 

 a very difficult operation. The dredge', anchored the boat several 

 times, and when brought up was full of sand. Hence representative 

 hauls at Stations 33, 34, and 35 were not obtained. At Station 33 

 only a few small crabs and broken shells. 



Stations 34 and 35. — Continuing the line of Station 33 and dredging 

 towards Small Sober Island. 



Depth, 13 to 18 fathoms. Bottom, sand. 



At both stations the dredge stuck in the sand and nothing was 

 obtained. 



Station 36. — ^Along north end of Sober Island, near shore. 



Depth, 8 to 10 fathoms. Bottom, rock, stones, and sand. 



Many Echinoids of a deep peacock blue colour. Several Astro- 

 pecten zebra. Holothuria marmorata. Many sponges, containing 

 Alpheids [Alpheus minus, Alpheus bis-incisus) , Synapta striata, 

 Dromia, worms, brittle stars, and CaUianassids. Metapeneus 

 inogiensis. One specimen of a solitary coral. Many broken shells 

 and Halimeda. 



Station 37. — ^Malay Cove, nearly half a mile south-west of Round 

 Point. 



Depth, 7 fathoms. Bottom, gravel and stones. 



One Holothuria marmorata. One Gucumaria imbricata. One 

 Parapeneus stylifera (1). Several Astropecten zebra. 



Station 38. — Malay Cove, half a mile south of Round Point, near 

 the shore of Sober Island. 



Depth, 5 fathoms. Bottom, gravel and stones. 



Numerous sponges and Halimeda. Alpheids, worms, and brittle 

 star fishes mixed with the sponges. Many blue Echinoids. Holo- 

 thuria marmorata. This haul is very similar to the one at Station 36. 



Station 39. — Centre of Malay Cove, 600 yards west of Station 38. 



Depth, 4 fathoms. Bottom, sand. 



Very similar to Stations 36 and 38, but no blue Echinoids present. 

 Large Ophiuroids and several compound Ascidians. Numerous 

 Synapta striata in the sponges. 



Station 40. — In Orlando Cove, between the north-east side of 

 Sober Island and Small Sober Island. 



Depth, 7 fathoms. Bottom, sand. 



Many shrimps {Periclimenes spinigerus), on a large dark purple 

 sponge. This sponge was pecuUar in having a sticky jam-like 

 secretion, which stained the hands. 



Station 41. — Off south-east side of Small Sober Island, about 300 

 yards from shore. 



Depth, 9 fathoms. Bottom, sand and gravel. 



Many sponges, including black, purple, and brick- red. Alplieus 

 bis-incisus in crevices of yellow sponge. Several corals. Many 

 Sipunculids and Polychaetes from interior of the sponge.
