BRYOZOA OF THE PHILIPPINE REGION 543 



not orthogonal and adjacent to a tube. If these two species lived 

 together their separation would be very difficult. 



Occurrence— D. 4807. Cape Tsiuka, Sea of Japan; 41° 36' 12" N.; 

 140° 36' E. 



Cotypes— Cat. No. 8377, U.S.N.M. 



TUBULIPORA (?) GRANDIPORA, new species 



Plate 83, figs. 1, 2 



Description. — The zoarium encrusts bryozoa. The tubes are large, 

 distinct, isolated or united in irregular fascicles; the peristomie is 

 very long, quite erect, rectilinear or curved. 



Measurements. — Diameter of peristome, 0.30 mm., and length of 

 peristomie, 0.60 mm. 



Affinities. — The form of the colony depends on the substratum; it 

 is elongated on flat and large surfaces (fig. 2); it is contracted on 

 small surfaces and almost entirely surrounds them (fig. 1). 



This species differs from Diaperoecia transversalis in the large 

 dimensions of its peristomie. It differs from Tubulipora phalangea 

 Busk, 1875, in its peristomial dimensions, which are twice as great. 



We have not discovered the ovicell and it is by analogy only that 

 we class it in Tubulipora. 

 Occurrence. —

48' 10" E.; 21 fathoms; co. S., Sh. 

 D. 5577. Mount Dromedario, north of Tawi Tawi Group; 5° 

 20' 35" N.; 119° 58' 51" E.; 240 fathoms; crs. S. 

 Cotypes.— Oat. No. 8378, U.S.N.M. 



Genus IDMONEA Lamouroux, 1821 



IDMONEA AUSTRALIS MacGillivray, 1884 



Plate 84, figs. 4-6 



1884. Idmonea australis MacGillivray, Prodromus Zoology Victoria, dec. 7, 

 p. 30, pi. 68, fig. 2. 



Measurements. — Diameter of peristomes, 0.14-0.16 mm.; distance 

 of fascicles, 0.30; width of branches, 1.00; and number of tubes to 

 fascicle, 4. 



Aifinities. — Our specimens arc striated longitudinally, but this 

 character is little visible, for the transverse wrinkles are quite visible 

 and numerous; the latter are much curved. The fascicles project 

 beyond the zoarial margins. 



Our specimens are very long and narrow. Some of them are 

 colored a brick red. We have not found the ovicell. It is a species 

 of shallow water.
