286 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 14 



There are no spines, no avicularla nor any other type of decoration ; 

 multiporous septulae are present in the thin lateral and distal walls, 



Hincks descrihed the species as C. praelonga from Port Philip Heads, 

 Australia, in 1884, overlooking the fact that MacGillivray had already 

 described it as Lepralia longipora. There are slight differences in their 

 descriptions and figures, but Hincks has accepted the synonymy. 



The species also bears considerable resemblance to "Monoporella" 

 waikiipurensis Waters (1887:50) from the "newer Pleistocene" of New 

 Zealand, which Canu and Bassler (1929:158) have reported as a recent 

 species from the Sea of Japan and which has never been properly allo- 

 cated. It cannot possibly be assigned to Monoporella which is an anascan 

 genus ; its characters suggest Cyclicopora as the proper genus. 



Hancock Stations: 275, Raza Island, Gulf of California, 28°44'00'' 

 N, 113°00'00"W, 40 fms; 1250-41, 1251-41 and 2160, south of San 

 Benito Islands, west of Lower California, 44 to 81 fms: and 450, Gala- 

 pagos Islands, 0°55'00''S, 90°30'00"W, 60 fms. Also a fine series 

 received from the Kenyon-Williams expedition to the San Benito Islands. 



Family GatenicelHdae Busk, 1852 



Erect, jointed, branching colonies, often with radicles for attachment. 

 Zooecia all facing the same way, one, two or three to an internode. Ovi- 

 cells or gonozooecia in different positions according to the genus. Avicu- 

 laria usually present. 



The family, which is abundant in the Australian seas, is scarcely 

 represented north of the equator and hitherto no species has been recorded 

 from the western coasts of the Americas. 



Genus VITTATICELLA Maplestone, 1900 



Characterized by the presence of a vitta (a longitudinal groove with 

 pores) on either side of the front. Occasionally very minute pores on the 

 frontal surface. The ovicell, which is surrounded by a "beaded border," 

 is rather deeply embedded in the base of the next distal zooecium, which 

 m this genus is functional and not reduced to a kenozooecium. Genotype, 

 Cdoporellainsignis MacGillivray, 1895:18.
