Species 21. (Mus. Cuming.) 



)elphinula clathrata. Delph. testd subdiscoided, 

 anfractibus rotundatis, carinulis transversis et longi- 

 tudinalibus equidistantibus regulariter clathratis ; la- 

 bro incrassato, marginato ; umbilico peramplo. 



rHE latticed Delphinula. Shell somewhat discoid, 

 whorls rounded, regularly latticed with equidistant, 

 transverse and longitudinal keels ; lip thickened, 

 marginated ; umbilicus very large. 



Reeve, Pro. Zool. Soc, 1843. 



Hab. Island of Corrigidor, Bay of Manila (found in 

 coarse sand at the depth of seven fathoms) ; Cuming. 

 A small species with a regularly latticed surface. 



Species 22. (Mus. Cuming.) 

 Delphinula Cobijbnsis. Delph. testd turbinatd, mi- 

 nutd ; anfractibus convexis, carinulis transversis et 

 longitudinalibus equidistantibus regulariter clathratis ; 

 umbilico mediocri ; labro simplici. 

 The Cobija Delphinula. Shell turbinated, very 

 small ; ribs convex, regularly latticed with equidi- 

 stant, transverse and longitudinal ribs ; umbilicus 

 middling ; lip simple. 

 Reeve, Pro. Zool. Soc, 1843. 



Hab. Port of Cobija, Peru (found under stones in rocky 

 places at low water) ; Cuming. 

 The sculpture of this shell, familiarly known to Mr. 

 Cuming as " his little Cobija species," is exactly similar 

 to that of the D. clathrata ; it is however much less dis- 

 coid in form, the whorls are not so round, the umbilicus 

 is smaller, and the lip is not marginated. 



Species 23. (Mus. Cuming.) 

 Delphinula syderea. Delph. testd turbinatd, spird 

 plano-concavd, apice inter dum rosaceo ; anfractibus 

 angulato-convexis, tuberculis muricatis, in seriebus 

 duabus ant pluribus, radiatim stellatis ; labro incras- 

 sato, marginato. 

 The starry Delphinula. Shell turbinated, spire 

 flatly concave, apex sometimes stained with pink ; 



whorls angularly convex, radiately starred with 

 two or more rows of prickly tubercles ; lip thick- 

 ened and marginated. 



Reeve, Pro. Zool. Soc, 1843. 



Hab. Island of Camiguing, Philippines (found under 

 stones at low water) ; Cuming. 



The leading feature of this species, and which is 

 especially prominent in young specimens, is its peculiar 

 star-like display of tubercles , the concave flatness of the 

 spire is also remarkable. 



Species 24. (Mus. Cuming.) 



Delphinula radiata. Delph. testd orbiculari, depresso- 

 turbinatd, albido-luteotd, maculis coccineis perpaucis 

 vivide pictd ; anfractibus angulato-convexis, corru- 

 gato-slriatis ; peripheric serie unicd tuberculorum ra- 

 diatim slellatd, tuberculis comprcssis, prominentibus, 

 mucronatis, carinuld muriculatd infra; labro simplici. 

 The radiated Delphinula. Shell orbicular, depressly 

 turbinated ; whorls angularly convex, striated in a 

 wrinkled manner ; periphery radiately starred with 

 a row of very prominent, compressed, sharp-pointed 

 scales, having a fine prickly-scaled keel encircling 

 the shell beneath ; lip simple. 

 Kiener, Iconographie, pi. 4. f. 9. 

 Hab. Indian Seas; M. Janelle. 



The Delphinula radiata, though only lately described, 

 has been long known in this country by the richly co- 

 loured specimen here figured, from the collection of the 

 late Mr. George Humphreys. The locality attached to 

 it by that veteran conchologist is " West Indies," but 

 as the above-mentioned place is quoted by Kiener on 

 the authority of M. Janelle, it cannot well be disputed. 



Species 25. (Fig. a & b, Mus. Cuming.) 

 Delphinula caxcellata. Delph. testa subdiscoided, 

 spird depressd ; anfractibus liris transversis et longi- 

 tudinalibus subdistantibus elegantissimt crenulatis, 

 liris tribus centralibus prominentioribus, subspinosis ; 

 labro simplici.
