22 THE NAUTILUS. 



Aug. 8, 1912, by A. A. Hinkley. Aside from several very young 

 ones, the sex of which could not be ascertained, there were two large 

 males, and a gravid female, discharging glochidia. The date (Aug. 

 8) indicates the end of the breeding season. 



Anal opening separated from the supraanal by a short mantle- 

 connection, but in the largest male the two openings are united, the 

 mantle-connection being undoubtedly torn. Anal with the inner 

 edge almost smooth, branchial with distinct papillae. Posterior 

 margins of palpi connected for about one-half of their length. 



Inner lamina of inner gills free from the abdominal sac, except at 

 anterior end. In the female, all four gills are marsupial. The 

 shape of the placentae could not be observed, since the female was 

 discharging, and the glochidia filled the suprabranchial canals and 

 cloacal cavity in large, loose masses. But many glochidia were yet 

 lodged in all four gills. 



Glochidia subovate, higher than long, of medium size. Length, 

 0.20; height, 0.24 mm. 



Color of soft parts apparently of the whitish type. 



This is a true Quadrula, allied in its shell characters to Q. lach- 

 rymosa (Lea). From Q. pustu/osa (Lea) it is rather sharply dis- 

 tinguished by the glochidia, which are considerably larger in the 

 latter species, 0.23 X 0.30 according to Lefevre and Curtis (Journ. 

 Exp. Zool., 1910, p. ( J8, fig. 1, F), while I found them (in speci- 

 mens from "West Virginia) to be 0.22 X 0.29 mm.

NOTES. 



ANOTHER GIANT SQUID IN MONTEREY BAY. Since the publi- 

 cation of my note in the NAUTILUS of February, 1912, I have been 

 informed of the occurrence of another big squid in the same region 

 as the one previously reported. Hoping to secure further details, I 

 laid the note to one side, but as no further data have been forth- 

 coming, it may be well to publish the record that it may not be lost. 

 Such information as I have been able to obtain was furnished to 

 Dr. Harold Heath of Stanford University by Mr. K. Hovden, Man- 

 ager of the Booth Canning Company at Monterey, who happened to 

 be fortunate enough to see the specimen.
