sinuses and much wider and shorter deltidial phxtes. T. crossei 

 Davidson grows much larger, is less coarsely striated, and while its 

 genital sinuses are minutely reticulated the two symmetrical groups 

 are widely separated by a space free of sinuses.

Type locality. — Sagami Bay, Japan. 



On a bunch of coral rock hooked up by fishermen from 60 fathoms 

 off Redondo, California, several brachiopods were attached which 

 seemed to me different from the Laqueus californicus usually found 

 there, and after my return to Washington, Dr. R. H. Tremper, the 

 collector, generously donated one of them to the United States 

 National Museum. It was a great surprise to find the Japanese 

 species on our coast, but there seems no doubt about the identifica- 

 tion of the shell. The dried animal showed the reflected part of the 

 brachia comprising the median coil was not, as usual, united by a 

 thin band of tissue but the right and left brachia appeared to be 

 quite free from one another medially except at the posterior com- 

 missure; while in the nearest related species, T. callinome, a mem- 

 brane exists between the two arms of the reflected loop and back 

 over the shelly loop to the vicinity of the adductors. The spiculae 

 were remarkably visible under a hand lens in beautiful stellate 

 forms and profusely invading the tissues everywhere. The genital 

 sinuses comprise two groups separated distinctly from one another 

 by a space entirely free from sinuses and each group comprising 

 about one half the space of its side of the valve, extending nearly 

 to the anterior margin of the valve and composed of a multitude of 

 small reticulations densely carpeted with spiculae. The species 

 reported by Fischer and Oehlert from Magellan Straits, under this 

 name, is said by Blochmann to be distinct. 



TEREBKATULINA CALLINOME, new species. 



Shell resembling T. crossei Davidson on a smaller scale, but more 

 sharply sculptured, whitish or pale salmon-colored, glistening, the 

 radial sculpture of sharp striae with flattish wider interspaces (not 

 raised as in T. japonica) ; the foramen large, the deltidial plates small, 

 not coalescent medially; brachial valve with slender brachia with 

 rather short filaments, the reflected arms united hy a membrane as
