There is a wide amount of varifttion among the examples of the above species 

 in the present series. Typical short and broad forzns are common, but the tendency 

 is for the test to continue to develop far beyond the ordinary adidt form, and to 

 put on a lengthy series of chambers, which in their greater inflation resemble those 

 of T. agglutinnns. This feature was also noticed by Mr. Millett (loc. supra cit.) in 

 regard to the Malay specimens ; and he says in regard to them. " In the majority 

 the earlier-formed portion of the test resembles sagittula, the later portion agglu- 

 tinans.'" In all three soundings in which this species occurs a large proportion of 

 the shells have a Spiro-plccta-Wke commencement — i.e., with a 1-whorled spiral 

 having a central megalosphere, and thus belonging to form A. 



Distribution. — Widely dispersed. Common in moderately sliallow water. Re- 

 corded by the writer from Great Barrier Island, at 110 fathoms. 



Present Occurrence. — (Jff the Snares ; 60 fathoms ; common. Twenty miles 

 north of Auckland Island ; 85 fathoms ; common. Ten miles north of Enderby 

 Island : 85 fathoms : very common.

An arenaceous variety, corresponding in external form with tlie hyaline jugosa 



of Brady. 



Distribution. — Fossil in the Pliocene of England and Italy. Found recent only 

 by Mr. Millett in the Malay Archipelago. 



Present Occurrence. — Off the Snares ; 60 fathoms ; rare.

 Distrihution. — The type example came from the West Indies. Some allied 

 forms, as pointed out by Millett, occur in Oolitic and Tertiary strata. 



Present Occurrence. — Twenty miles north of Auckland Island ; 85 fatht)ms ; 

 very rare.
