CORRIGENDA and ADDENDA to previous Records of Spongise. 
Schulze, F. E. (61) and (62) Zool. Rec. 1900. The volume of the Denk. 
Ak. Wien, in which these memoirs are published, having now reached 
English libraries, it is now possible for the Recorder to quote the 
original pagination. Schulze (61) is Denk. Ak. Wien lxix, pp. 497- 
506 ; Schulze (62) is t. c. pp. 311-324; hence 496 should be added to 
the number of each page cited, in the case of the former, and 310 in 
the case of the latter. 
Topsent, E. (60) Zool. Rec. 1901. This memoir was included in the 
Record for 1901 on the evidence of a copy received from the author, 
which bore that date. In the series of the “ Expedition Antarctique 
Beige,” however, it is dated 1902. 
Ephydatia olchonensis n. sp., p. 37, and Spongilla microgemmata n. sp., 
p. 38, Zool. Rec. 1901, Sponges. These two nn. spp. were wrongly 
attributed to Korotneff (33) Zool. Rec. 1901, in whose memoir they 
were mentioned as new. They should be attributed to Svartzevsky 
(59) and (60) of the present Record, whose memoirs were not accessible 
to the Recorder before this year.
