HALIOTIS. 26 



9G, with a few laminn,ted wrinkles, from this species. The 

 ang-iilar markings, cut up into a sort of reticulation and 

 intermingled in some varieties with white specks, constitute 

 the peculiarity of the species, which is flattened and very 

 angular at tlie dorsal ridge. 



31. Janus, f. 81, Reeve. — Testa //. reticulatce similis, spi- 

 raliter striata, medio et versus suturam aurantio-subviridis, 

 disco versus angulum dorsalem late albo fasciato, maculis 

 magnis purpureo-fuscis picto. — It is with some doubt that I 

 treat this species as distinct from the preceding, but the 

 dorsal disc is spirally divided into two parts as to colour, 

 namely, the half nearest the spire dull orange, and that near 

 the ridge white with dark spots. 



32. SPECIOSA, f. 107, 108 (?), 123, Reeve.— Testa oblongo- 

 ovata planulata, medio depressa, spiraliter sublsevigatim 

 striata, fulva, maculis maximis rubris nigro-marginatis picta, 

 margine tuberculifero valde angulato ; foraminibus par- 

 viusculis, approximatis. — Oblong-ovate, rather flat, depressed 

 in tlie middle, variegated with red or orange patches of 

 colour, the patches being bordered with dark lines. The 

 perforated tubercles are rather small. It is not easy to fix 

 the bounds of this species, but it is probable that the very 

 similarly formed shell taken haphazard by Mr. Reeve for 

 H. striata, Linn. f. (108), belongs to it, although the style 

 of variegation is unlike. 



33. CocciNEA, f. 64, 95, 120, Reeve. — Testa oblongo- 

 subovata, aetate juniori rugosa, vivide coccineo variegata, 

 deinde spiraliter subrugose lirata, concentrice rude plicata 

 interstitiis tenuissime striatis, area marginali spiraliter lirata. 

 — As in the case of many other species when the early character 

 differs from the after-development, the change takes place at 

 various stages. Thus we have a shell, say an inch and three- 

 quarters long, retaining the early crumpled scai'let-mottled 

 character, and another large brown shell sculptured with flat- 

 tened ridges, and only half an inch of the bright variegated 

 red towards the spire. The specimen figured as 120 is from 

 the late Mr. Taylor's collection, and is peculiar in the dupli- 

 cate character of some of the ridges and the widening of the 

 shell towards the anterior termination. 



34. ZELANDiCA, f. 90, Reeve. — Testa ovato-oblonga, fulva, 

 maculis trigonis fuscis variegata, tenuiter liratim in.Tqualiter
