lane Hill. They probably belong to Woods' species in spite of the 

 apparent absence of nodes, though this lack of ornament suggests 

 affinity with B. bally i, Woods (which apparently is rare, and 

 characterised by a very distinct type of suture-line), or with other 

 smooth species of Baculites. 



The examples that Crick * records from the South Branch of the 

 Manuan Creek, apparently related to B. capensis, Woods, are similarly 

 poorly preserved and more or less indeterminable specimens. 



Specimen No. 5484, containing at least twenty to thirty examples, 

 has in addition to B. capensis, and forms close to B. bailyi, a number 

 of more or less unidentifiable fragments that had best be included 

 here. One example has the mouth border complete, but no initial 

 whorls were discovered in this block, the reason being, perhaps, that 

 this coarsely sandy, conglomeratic matrix (with pebbles of fossil wood) 

 was not suitable for the preservation of so delicate a structure. The 

 mode of life in the embryonic stage, also, possibly was different 

 (planctonic ?) from the mud-boring existence of the adult shells.

A small portion of a Baculites (No. 5480), 38 mm. in length and 

 forming part of the body-chamber, differs from the many examples of 

 B. capensis that occur in the same rock, merely in having the nodes 

 closer, there being six in the length represented, as against half as 

 many in Woods' species. The nodes are rounded, as in B. capensis, 

 and the cross-section also, perhaps, resembles that of B. asper, Morton 

 (in Romer), and of B. capensis more than it does that of B. aspero- 

 anceps. The form here described probably is only a variety of B. 

 capensis, comparable to the Texas form in the closer spacing of the 

 nodes. It may be added that some of the examples included in B. 

 capensis (e. g. No. 5490, and No. 5470) have the nodes closer than the 

 (larger) Pondoland examples, and thus are transitional to the form 

 here described.
