 Gulf of California, 51-54 fathoms.

Gonosome. — (Not previously described.) There is a sex differentia- 

 tion in the gonangia similar to that in some species of Plumularia. Both 

 types grow from the face of the hydrocladial processes throughout a large 

 portion of the stem. The female gonangium is stout for its length, in the 

 one direction, almost as broad as long, but in the other diameter, the dif- 

 ference is more definite, so that the whole gonangium is flattened ; it is 

 obovate, the distal end obtuse, but slightly rounded, the proximal end 

 tapered to a short pedicel. In the male, the gonangium is elongated ellip- 

 tical, much like that in Plu?nularia corrugata Nutting, or P. lagenifera 

 Allman. These male specimens are more slender than those described 

 originally and the cauline nodes are quite distinct. 



Distribution. — 1 mile south of East Point, Santa Rosa Island, 15-16 

 fathoms; 1 mile south of west end of Anacapa Island, 26 fathoms; San 

 Francisquito Bay, Gulf of California, 20 fathoms; Puerto Refugio, 

 Angel de la Guardia Island, 51-54 fathoms; off Willard Point, Gonzaga 

 Bay, 30-40 fathoms.

 Fraser, ibid., 3, 1938, p. 135. 

 Distribution. — J^ mile south of west end of Anacapa Island, 25-26 

 fathoms; 1>^ miles north of Cedros Island, 55-60 fathoms; 8 miles west 

 of Cedros Island, 64-65 fathoms; between Angel de la Guardia and 

 Mejia Islands, Gulf of California, 6-11 fathoms; south of San Esteban 

 Island, 25 fathoms. 



Genus GLADOGARPUS 

 Gladocarpus (?) gracilis, new species 

 Plate 36, Fig. 39 

 Trophosome. — A colony, 10 mm high, is simple, slender, and un- 

 branched ; the distal half of the stem is thecate and corresponds to a com- 

 plete hydrocladium in other species. Just proximal to the first thecate
