62 THE SPONGES. 



tially similar to the anchor-like forms above described. The number of 

 lateral spines is 2-5, and they may be straight or curved. The teeth of 

 the anchor never show a spiral curvature, as they do in some of the spicules 

 of F. mexLcana. Similar anchor-like clavulae with lateral spines are de- 

 scribed by Topsent (1901, p. 466) for Farrea iveltneri Tops., in which the 

 hexaster is a discohexaster. 



Farrea acideata F. E. Sob. was taken 47' 29' N., 125° 33' 30" W., at a 

 depth of 1163 m. 



Farrea, sp. 



At Station 34^0, 8 specimens, and at Station 3430, 2 specimens, of 

 Farrea were taken. In these only the dictyonal framework is preserved, 

 and a closer identification is therefore impo.ssible. 



Schulze (1887, p. 278) mention.s that in F. occa he has occasionally found 

 the terminal openings of the tubes covered in with porous plates. In one 

 of the specimens here recorded, I find that two of the openings are nearly 

 closed in by such reticula. In each case a small aperture, which is rounded 

 and apparently natural, has been left near the edge of the original opening.

At Stations 3358, 33o9, and 3380, 19 specimens were taken referable to 

 this species. While they were all partially macerated, the free spicules 

 had been retained. These specimens differ from the type and from one 

 another in details, and fall into three well-marked groups which I designate 

 as subspecies. The specimens from Station 3380 constitute one of these 

 groups. Each of the other two groups includes specimens from both of the 

 other two stations. 



A dozen completely macerated specimens, agreeing with the above in 

 habitus and dictyonal framework, were obtained at the above stations and
