On Indian Deep-sea Trawling. 517 
Idiopholis Everetti, sp. n. 
Snout short and obtuse. Rostral narrow, deeper than 
broad ; no azygous shield between the internasals ; frontal 
once and a half as broad as long, as long as the prefrontals, 
less than half as long as the parietals ; six upper labials, third 
and fourth entering the eye, fifth largest and forming a 
suture with the parietal; anterior chin-shields only slightly 
longer than the posterior. Scalesin 15 rows. Ventrals 133 ; 
anal entire; subcaudals 25. Uniform dark bluish grey, 
ventral surface of head and neck slightly paler. 
Total length 155 millim. 
Hab. Sawa, N. Borneo (A. Everett). The only specimen 
is preserved in the British Museum (Natural History). 
The species differs from J. collaris (Mocq.) by its broader 
frontal, by the absence of an azygous shield between the 
internasals, by its shorter tail, and by its coloration. 
LXVI.—Natural History Notes from the Royal Indian Marine 
Survey Ship ‘ Investigator, Commander T. H. Heming, 
R.N., commanding.—Series III., No. 5. An Account of the 
Trawling Operations during the Surveying-season of 1900- 
1901. By A. F. McArpte, B.A., M.B., Capt. I.M.S., 
Surgeon- Naturalist to the Survey. 
DurInG the season fourteen deep-sea trawls were made in 
over 100 fath., of which eleven were in water over 500, and 
five in water over 1000 fath. deep. This may seem to be no 
very great number for some months’ work, but it must be 
borne in mind that surveying is the principal work of the 
R.I.M.S. ‘ Investigator,’ and this takes up so much of her 
time that trawling must necessarily be to her of secondary 
importance and relegated more or less to the background. 
Except, too, when she is on her way to the surveying- 
ground, or from one surveying-ground to another, she is 
working between the coast and the hundred-fathom line, 
rendering deep trawling impossible. A combination of cir- 
cumstances is thus necessary before deep-sea trawling can be 
undertaken on the ship—she must be in deep water, have 
time to spare for the operation, and favoured with fine 
weather. 
Of the collections made during the season the Fishes 
and the Crustacea (with the exception of the Paguride) 
were worked out during the recess; the Mollusca, Starfishes,
