Report on Foraminifera. By F. W. Millett. 259 



In the Malay Archipelago it has been observed only at Station 

 13 in Area 1, and the few examples are small and of arrested 

 growth. 



There are three ' Challenger ' Stations for this form given by 

 Brady : off Gomera, Canaries, 620 fathoms ; off Kandavu, Fiji, 

 210 fathoms ; and off Eaine Island, Torres Strait, 155 fathoms. 

 He also states that it has been reported from the shores of the 

 Adriatic, at Kimini and Lido. 



Amphicoryne Schlumberger. 



Of all the compound forms this is perhaps the most difficult 

 to deal with in a satisfactory manner, for not only is it in many 

 instances hard to determine the genera of the component parts, 

 but there are numerous monstrosities which so nearly resemble 

 the types that it is difficult to distinguish between them. 



Although this genus was instituted to include the forms com- 

 pounded of Cristellaria and Nodosaria, the Cristellarian portion, 

 so far as has been observed, is always of the crepidula type and 

 consequently passes by imperceptible degrees into the genus 

 Vaginulina. It is doubtful if any good purpose would be served 

 by the adoption of the genus Nodosariopsis, and although Prof. 

 Silvestri is quite in order in giving a generic name to the com- 

 bination of Vaginulina and Nodosaria, in practice there would be 

 a great difficulty in keeping the two genera distinct ; besides this, 

 there would be the inconvenience of removing the species falx 

 from the genus Amphicorync, of which it has hitherto been con- 

 sidered the type. In this state of uncertainty it will perhaps be 

 convenient to assign to Amphicoryne all the forms having the initial 

 portion Cristellarian or Vaginuline.

Surface of test smooth ; earlier portion, a compact variety of 

 Cristellaria crepidula ; later portion resembling Dentalina com- 

 munis. Length 0' 90 mm. 



This smooth form is very rare in the Malay Archipelago, and 

 has been found only at Station 30 in Area 2. 



It is quite possible that the three figured examples referred to 

 in the above list of synonyms may be monstrosities, rather than 

 members of the genus Amphicoryne. Williamson writes of his 

 example, " Fig. 57 represents a curious monstrosity, in which the
