NO. 2 OSBURN: eastern pacific BRYOZOA — CHEILOSTOMATA 431 



and a small bicuspidate lyrula ; the peristome is high and thin and unites 

 slightly with the proximal corners of the ovicell. The secondary aperture 

 is asymmetrically ovate. Proximal to the aperture and asymmetrically 

 placed is a comparatively small avicularium with the long-triangular 

 mandible directed more or less laterally; the avicularian chamber only 

 slightly elevated. 



The ovicell is prominent, hemispherical, smooth with large pores and 

 with a low collar around the base ; 0.40 mm wide by 0.25 to 0.30 mm 

 long. 



This is a striking species, due to its smooth appearance, as the only 

 decoration of the front is the delicate reticulation. 



Type, U. S. Nat. Mus., 11032. 



Type locality, Albatross Station 5695 (cruise of 1911), Lower Cali- 

 fornia, 534 fms. 



It is named in memory of my former friend. Dr. Charles Haskins 

 Townsend, Naturalist on the "Albatross" from 1886 to 1896 and tem- 

 porarily on the cruise in 1911 when this species was dredged.

Zoarium encrusting, smooth and glistening. The zooecia are moder- 

 ately large, 0.65 to 0.90 mm long by 0.45 to 0.55 mm wide, ovate, 

 slightly inflated ; the frontal thin and smooth, later becoming granulated, 

 a row of areolar pores separated by short costules ; a crescentic area proxi- 

 mal to the aperture is delicately outlined. The aperture is nearly round, 

 about 0.18 to 0.20 mm in either direction; the cardelles distinct and 

 pointed and there is a slender bifid lyrula with laterally directed points. 

 The peristome is thin and more or less elevated, connected with the 

 avicularian chamber on one side and forming a low lappet on the oppo- 

 site side. The avicularian chamber is small and low, asymmetrical and 

 connected with one areolar pore, the mandible is long-triangular and 

 directed laterally; when completely developed the mandible appears as 

 if lodged just within the rim of the peristome and curved to conform 

 to it.
