35. Isapis fenestrata. 



I. testa I. ovoideee forma et indole simili ; carinis ix. acutis (quarum 

 iv. in spira monstrantur) cincta ; iuterstitiis duplo latioribus, con- 

 cinne quadratim decussatis, lirulis radiantibus acutissimis ; anfr. 

 postice tumentibus, suturis valde excavatis ; peritremate continuo ; 

 labro a carinis pectinate ; labio parietem parum attingente, medio 

 calloso; umbilico angusto. Long. -18, long. spir. -13, lat. '19, 

 div. 70°. 



Hab. Necah Bay {Swan) ; S. Diego and Sta. Barbara Island 

 {Cooper). 



Dr. Cooper's shells are much smaller than those from the 

 Vancouver district, which are white and eroded, vailing much 

 in the size of the umbilicus. 



36. Alvania reticulata. 



A. testa parva, gubturrita, rufo-fuscn, marginibus spine rectis ; anfr. 

 nucleosis ii. et diniidio, naticoidcis, Icevibus, tumentibus, apice 

 mamillnto; norm, iii., tumidis, suturis impressis ; liris augustis, 

 diiijtantibus, spiralibus circ. xii. (quarum iv.-vi. in spira mon- 

 strantur), ct lirulis radiantibus, supra transeuntibus, hand nodulosis, 

 secundum interstitia incurvatis, eleganter exsculpta ; iuterstitiis 

 altis, quadratis ; peritremate continuo, subrotundato, acutiore. 

 Long. '085, long. spir. '05, lat. -OJ, div. 30^. 



Hah. Neeah Bay; two specimens in shell- washings {Swan). 



37. Alvania filosa. 



A. testa A. reticulata indole et colore, baud sculptura, simili ; multo 

 majore, clongata; anfr. nucl. ?... (detritis), norm. iv. ; striis parum

XLVIL — Description of a new Species o/ Eublepharis. 



By Dr. Albert GCnther. 



Eublepharis fasciolatus. 



Very similar in general habit to E. Hardwickii, but with 



the tubercles much less numerous and separated by granular 



interspaces as wide as the tubercles themselves. Opening of the 



ear wide. Nine upper and ten lower labials ; two chin-shields 



larger than the first lower labial. The scales of the middle of 



the belly forui twenty-four longitudinal series. A series of 



fourteen pores across the prseanal region.
