have been referred, with some reservation, to this species. 

 They have the form of a symmetrical cone, with the inferior 

 surface depressed. The presence of only two examples, and 

 these of very minute size, makes a definite determination 

 somewhat difficult, 



Fulviuidina scahricula, Chapman. — This form was de- 

 scribed by Mr. Chapman from the Batesford Limestione 

 (Moorabool Kiver, Vic). The examples from Lilydale are 

 more deeply pitted than the type, and are moderately common 

 in No. 4 bore. 



liotalia paplllosa, var. comprefis'iuscula, Brady. — Rotali- 

 form shells with strongly-developed surface ornament occur 

 in both bores, and, in varying numbers, at all depths 

 examined. They may be said to be of ^. ffi2)iUosa type, but 

 comprise variations from that form in the direction of other 

 species. The most prevalent features are those of I^ . papillosa, 

 var. §o?upressiiisc7(Ja, but some specimens show a close resem- 

 blance to Ji. schroeteriana, especially in No. 4 Bore, at 300 

 feet to 318 feet horizon. In the Kruger Dam Bore, and also 

 in No. 4 Bore to some extent, strongly-built examples occur 

 which approximate to the 7?. clathrata, Brady, style of orna- 

 ment, but with some differences. In this latter case the seg- 

 ments of the inferior side are angulated, radially, as ridges, 

 and are marked by a strong limbation, while between the 

 limbate ridges are numerous transverse ridges. In some 

 specimens, again, one to three spines are developed on the 

 peripheral margin, akin to those in /?. calair, d'Orb. The 

 variations indicated above may be but varietal in tlieir occur- 

 rence, or fuller research may give them a specific value. 



PolystomeUa verriculata, Brady. — Two examples of this 

 very distinct and interesting species were obtained from the 

 lower portion of No. 4 Bore. It also occurred sparingly in 

 the lower beds of Muddy Creek. 



Amphi.sfe(/uia le>isonii, d'Orb. — This form is very 

 abundant in the lower levels of No. 4 Bore, but appears 

 to be absent from the upper levels, as well as from the Kruger 

 Dam Bore. This restricted distribution, limiting an abundant 

 form to one particular horizon, is somewhat remarkable, and 

 may have some geological significance. The specimens attained 

 fairly large size, but are not equal, in this respect, to the 

 very large examples of this species which occur at Muddy 

 Creek. Like those found in the last-named locality they have 

 been altered to brown ocherous-pseudomorphs. 



The Foraminifera in the above list number about seventy- 

 nine species, and, on the whole, exhibit a facies that showal 

 relationship with the Muddy Creek (Vic.) lower beds (Bal- 

 combian), rather than with the Adelaide and Aldinga
