Amphisphyra hiemalis. Couth. 



Var. Loveni. nob. 

 PI. £11, Fig. T. s. 



Spiret er om end noget nedsunket dog tydeligt i 2 

 Vindinger. 



Paa St. 240 — 1000 Favne forekom 5 Exemplarer, 

 der alle har tydeligt Spir. hvorimod et 6te har dette skjult. 

 saaledes som regelmæssig er Tilfælde hos den udviklede 

 Amphisphyra hiemalis, Couth. Størrelsen var dog omtrent 

 den samme hos alle. nemlig omkring o.r.""". 



Dr. Jeffreys har gjort opmærksom paa, at det af 

 Loven observerede Spir hos Amphisphyra rjlobosa kun er et 

 Ungdomsstadie, men at det fuldstændig fbrsvinder senere, 

 naar Skallen udvikler sig. I dette Tilfælde beholder imid- 

 lertid det overveiende Antal igjennem sin hele Udvikling 

 Spiret.

Skallen hvid. tynd, oval. oventil truncat ; Vindingerne 

 2 1 , — 3 er synlige paa Spiret, eler ligger i Niveau med 

 Hovedvindingen; Suturen er grund rundt den apicale Vin- 

 ding, men tiltager senere i Dybde og ender i en fin Split; 

 Ventralvindingen har omtrent halve Mundaabningens Stør- 

 relse; Mundaabningen er piriform, meget udvidet forneden, 

 og sammenknebet, dog ikke tilspidset oventil; Læben er 

 sinuos, er forst udgaaende i en stump Vinkel og boier saa 

 i en noget indbugtet Liuie nedad, den nedre Ende er bredt 

 afrundet. 



Sculpturen (Fig. 10 «) bestaar af talrige fine Spiral- 

 stria', der ser ud som Dobbellinier, idet en s vagere og en 

 sterkere stadig vexler; Linierne er under stærk Forstørrelse 

 fint saugtakkede fremkommen derved, at de krydses af 

 talrige fine Væxtstriber. 



Tændeme ligne Philine finmarchia's. 



Kroens 2 Kalkplader er ualmindelig store; de er ikke 

 mindre end 2 / 3 Dele af Skallens Længde. 



Størrelse: 9'"'" Axiall.. 6.5 Diam. 



Forekomst: St. 18—400 Favn.'. 



Paa St. 87 og 295 — 488 og 1100 Favne — fandtes 

 nogle Fragmenter af en Philine, som synes at tilhøre 

 denne Art.

The spire although somewhat depressed is. yet, distinct 

 in 2 whorls. 



At station No. 24o. Depth 1000 fathoms, 5 specimens 

 were obtained, all of them having a distinct spire, whilst 

 a sixth specimen has it concealed, as is uniformly the 

 case with the developed Amphisphyra hiemalis, Couth. The 

 size was, however, nearly uniform in all. viz. about3. :>""". 



Dr. Jeffreys has pointed out that the spire in Am- 

 phisphyra i/lobosa observed by Loven, relates to an imma- 

 ture stage, and that it. subsequently, completelj disappears 

 when the shell is developed. In the present case, however, 

 the larger number retain the spire throughout the entire 

 development.

1877, pag. 9, fig. 19 a, b. c. 



Shell white, thin, oval, truncate superiorly. 2 1 L . — 3 

 whorls visible on the spire, which lies level with the Body- 

 whorl; suture 'shallow round the apicial whorl, but increases 

 in depth subsequently, andj terminates in a minute fissure. 

 The ventral whorl is about half the size of the aperture. 

 The aperture is piriform, much dilated below, contracted 

 above but not acuminated. The lip is sinuous, proceeding 

 first at an obtuse angle, then curving in a somewhat concave 

 line down-wards; the lower extremity is well rounded. 



The sculpture (fig. 10 a) consists of numerous, line. 

 spiral striæ appearing as double lines, owing to a faint one 

 and a more distinct one constantly alternating. Under 

 powerful magnification the lines appear minutely serrated, 

 from there being traversed by numerous fine lines of growth. 



The teeth resemble those of Philine finmarchia. 



The 2 calcareous plates of the gizzard are unconi- 

 monlv large, and measure, not less than, two-third parts of 

 the length of the shell. 



Size. Axial length, 9""". Diam., 6.5""". 



Habitat: Stat, No. 18. Depth, 400 fathoms. 



At stations Nos. 87 and 295 (Depth 4SS and 1100 

 fathoms) a few fragments of a Philine were found, which 

 appear to pertain to this species.
