HENRY SIDEBOTTOM ON LAGENAE OF THE SOUTH-WEST PACIFIC. 383" 



Lagena botelliformis Brady (PI. 14, iigs. 24-29). 



Lagena botelliformis Brady, 1884, p. 454, pi. 56, fig. 6. 



This again is to me an unsatisfactory species to deal with.. 

 Mr. Millett in his Malay Report considers it to Ido more nearly 

 allied to L. elongata than to L. glohosa. There is only one 

 example that agrees with Brady's Challenger figure. Locality: 

 Uncertain. 



Brady in his description of this form in the Challenger Report,, 

 p. 454, writes as follows : " Long, cylindrical, of even diameter, 

 arcuate," but in his scheme of the Genus Lagena, also in the 

 Challenger Report, it runs : " Cylindrical, or elongate, ovate, 

 bent." I think therefore we may include such forms as I 

 have figured. Chapman (1910), pi. 54, fig. 5, illustrates an 

 example from material collected by H.M.S. Penguin near 

 Funafuti, which is evidently of the same variety as those met 

 vdth in these gatherings. I have also a,nother large set of 

 Lagenae, picked out of material collected by the Penguin^ in 

 which this variety is also frequent. 



PI. 14, fig. 24 is nearest to Chapman's figure, but the tests 

 are more frequently similar to fig. 25. The aperture is placed 

 at the bottom of a shallow hood. Locality : It occurs at nearly 

 all the stations, including Nos. 1, 17, 19, 21, 29. 



PI. 14, fig. 26 is a very elongate variety. 



PI. 14, figs. 27, 28 appear to be weak, apiculate examples. 

 Locality : At No. 7, one example ; No. 11, five ; No. 14, one. 



PI. 14, fig. 29, I take to be a slight variation of fig. 24. There 

 are four sets of opaque, oval dots which run lengthwise, two rows 

 on either side. The base is inclined to be pointed. It is very 

 rare. Locality : At No. 3, one specimen ; No. 23. three. 



Fornasini (1894), under the heading of L. felsinea, ^giires, a 

 form that appears to be very near to Chapman's and to my 

 own fig. 24, the chief difference being that the aperture of his 

 specimen is fissurine. 



Lagena botelliformis Brady (?) var. nov. rugosa 



(PI. 14, fig. 30). 



Test cylindrical, curved, rugose. There is a short, tubular neck 



-with a small " boss " at the end, in which the aperture is placed. 



I cannot make out the nature of the shell-wall. The surface:
